+# Groove Basin
+
+Music player server with a web-based user interface inspired by Amarok 1.4.
+
+Run it on a server (such as a 512MB
+[Raspberry Pi](http://www.raspberrypi.org/)) connected to some speakers
+in your home or office. Guests can control the music player by connecting
+with a laptop, tablet, or smart phone. Further, you can stream your music
+library remotely.
+
+Groove Basin works with your personal music library; not an external music
+service. Groove Basin will never support DRM content.
+
+Try out the [live demo](http://demo.groovebasin.com/).
+
+## Features
+
+* Fast, responsive UI. It feels like a desktop app, not a web app.
+
+* Dynamic playlist mode which automatically queues random songs, favoring
+  songs that have not been queued recently.
+
+* Drag and drop upload. Drag and drop playlist editing. Rich keyboard
+  shortcuts.
+
+* Lazy multi-core
+  [EBU R128 loudness scanning](http://tech.ebu.ch/loudness) (tags compatible
+  with [ReplayGain](http://wiki.hydrogenaudio.org/index.php?title=ReplayGain_1.0_specification))
+  and automatic switching between track and album mode.
+  ["Loudness Zen"](http://www.youtube.com/watch?v=iuEtQqC-Sqo)
+
+* Streaming support. You can listen to your music library - or share it with
+  your friends - even when you are not physically near your home speakers.
+
+* MPD protocol support. This means you already have a selection of
+  [clients](http://mpd.wikia.com/wiki/Clients) which integrate with Groove Basin.
+  For example [MPDroid](https://github.com/abarisain/dmix).
+
+* [Last.fm](http://www.last.fm/) scrobbling.
+
+* File system monitoring. Add songs anywhere inside your music directory and
+  they instantly appear in your library in real time.
+
+* Supports GrooveBasin Protocol on the same port as MPD Protocol - use the
+  `protocolupgrade` command to upgrade.
+
+## Install
+
+1. Install [Node.js](http://nodejs.org) v0.10.x. Note that on Debian and
+   Ubuntu, sadly the official node package is not sufficient. You will either
+   have to use [Chris Lea's PPA](https://launchpad.net/~chris-lea/+archive/node.js/)
+   or compile from source.
+2. Install [libgroove](https://github.com/andrewrk/libgroove).
+3. Clone the source.
+4. `npm run build`
+5. `npm start`
+
+## Screenshots
+
+![Search + drag/drop support](http://superjoesoftware.com/temp/groove-basin-0.0.4.png)
+![Multi-select and context menu](http://superjoesoftware.com/temp/groove-basin-0.0.4-lib-menu.png)
+![Keyboard shortcuts](http://superjoesoftware.com/temp/groove-basin-0.0.4-shortcuts.png)
+![Last.fm Scrobbling](http://superjoesoftware.com/temp/groove-basin-0.0.4-lastfm.png)
+
+## Configuration
+
+When Groove Basin starts it will look for `config.js` in the current directory.
+If not found it creates one for you with default values.
+
+## Developing
+
+```
+$ npm run dev
+```
+
+This will install dependencies, build generated files, and then start the
+sever. It is up to you to restart it when you modify assets or server files.
+
+### Community
+
+Pull requests, feature requests, and bug reports are welcome! Live discussion
+in #libgroove on Freenode.
+
+### Roadmap
+
+ 1. Tag Editing
+ 2. Music library organization
+ 3. Accoustid Integration
+ 4. Playlists
+ 5. User accounts / permissions rehaul
+ 6. Event history / chat
+ 7. Finalize GrooveBasin protocol spec
+
+## Release Notes
+
+### 1.0.1 (Mar 18 2014)
+
+* Andrew Kelley:
+  * Fix race condition when removing tracks from playlist. Closes #160

+  * Fix Last.fm authentication
+
+### 1.0.0 (Mar 15 2014)
+
+* Andrew Kelley:

+    It uses [libgroove](https://github.com/andrewrk/libgroove) for audio
+    playback and streaming support.
+  * Support MPD protocol on (default) port 6600. Groove Basin now functions as
+    an MPD server.
+  * Fix regression for handling unknown artist/album
+  * Fix playlist to display artist name
+  * Plug upload security hole
+  * Groove Basin is no longer written in coco. Hopefully this will enable more
+    code contributions.
+  * Simpler config file that can survive new version releases.
+  * Simpler and more efficient protocol between client and server.
+  * Pressing prev on first track with repeat all on goes to end
+  * Automatic loudness detection (ReplayGain) using EBU R128.
+    - Lazy playlist scanning.
+    - Automatic switching between album and track mode.
+    - Takes advantage of multi-core systems.
+  * Faster rebuilding of album table index
+  * HTTP audio stream buffers much more quickly and flushes the buffer on seek.
+  * Fix volume ui going higher than 1.0.
+  * Fix changing volume not showing up on other clients.
+  * Native html5 audio streaming instead of soundmanager 2
+  * Streaming shows when it is buffering
+  * add meta charset=utf8 to index.html.

+  * Watches music library for updates and quickly updates library.
+  * Route dynamicmode through permissions framework
+  * Better default password generation
+  * web ui: fix current track not displayed sometimes
+  * upgrade jquery and jquery ui to latest stable. Fixes some UI glitches.
+  * static assets are gzipped and held permanently in memory. Makes the
+    web interface load faster.
+  * player: set "don't cache this" headers on stream
+  * Remove chat. It's not quite ready yet. Chat will be reimplemented better
+    in a future release.
+  * Remove stored playlist stub from UI. Stored playlists will be reimplemented
+    better in a future release.
+* Josh Wolfe:
+  * Converting the code to not use MPD

-  - duplicate detection and elimination
-    > if a song is byte for byte the same (check md5's) then ignore the
-      new song
-    > use heuristics to guess if songs are probably the same (using tags). if
-      we are reasonably confident that the songs are the same, delete the one
-      with the lower quality.
-    > if we're not confident enough, there will be an
-      api that lists possible duplicates and actions to resolve them.
-  - when a song is added to the library, automatically replaygain scan it
-    and the album from whence it came. Do this for update as well.
-* ability to add song to library by URL
-* take mpd's status into account. Make them editable?
-  - consume
-  - random
-* prepend '!' to a search word to NOT match the word. '\!' to literally match
-  '!'. '\\' to literally match '\'
-* ability to upload zip files
-* ability to upload via a url
-* ability to filter playlist
-* playlist management

+Changelog
+=========
+
+1.0.1 (March 18, 2014)
+----------------------
+
+.. What does this mean? 
+* Default import path includes artist directory.
+* Groove Basin now recognizes the `TCMP`_ ID3 tag as a compilation album flag. 
+
+.. _TCMP: http://id3.org/iTunes%20Compilation%20Flag
+
+Fixes:
+
+* Fixed Last.fm authentication.
+* Fixed a race condition when removing tracks from playlist.
+
+1.0.0 (March 15, 2014)
+----------------------
+
+In the 1.0.0 release, Groove Basin has removed its dependency on MPD, using 
+`libgroove`_ for audio playback and streaming support. Groove Basin is also not 
+written in `coco`_ anymore. Hopefully this will encourage more contributors to
+join the project!
+
+Major features include `ReplayGain`_ style automatic loudness detection using the 
+`EBU R128`_ recommendation. Scanning takes place on the fly, taking advantage of 
+multi-core systems. Groove Basin automatically switches between album and track 
+mode depending on the next item in the play queue.
+
+Chat and playlist functionality have been removed as they are not quite ready 
+yet. These features will be reimplemented better in a future release.
+
+.. _libgroove: https://github.com/andrewrk/libgroove
+.. _coco: https://github.com/satyr/coco
+.. _ReplayGain: https://en.wikipedia.org/wiki/ReplayGain
+.. _EBU R128: https://tech.ebu.ch/loudness
+
+Other features:
+
+* Groove Basin now functions as an MPD server. MPD clients can connect to port 
+  6600 by default.
+* The config file is simpler and should survive new version releases.
+* Client and server communications now use a simpler and more efficient protocol.
+* Rebuilding the album index is faster.
+* The HTTP audio stream buffers much more quickly and flushes the buffer on seek.
+* Streaming shows when it is buffering.
+* The web UI now specifies a `UTF-8`_ character set.
+* Groove Basin's music library now updates automatically by watching the music 
+  folder for changes.
+* HTTP streaming now uses native HTML5 audio, instead of `SoundManager 2`_
+* `jQuery`_ and `jQuery UI`_ have been updated to the latest stable version, fixing
+  some UI glitches.
+* Static assets are gzipped and held permanently in memory, making the web 
+  interface load faster.
+* Now routing Dynamic mode through the permissions framework.
+* Better default password generation.
+
+.. _UTF-8: https://en.wikipedia.org/wiki/UTF-8
+.. _SoundManager 2: http://www.schillmania.com/projects/soundmanager2/
+.. _jQuery: https://jquery.com/
+.. _jQuery UI: https://jqueryui.com/
+
+Fixes:
+
+* Fixed a regression for handling unknown artists or albums.
+* Fixed play queue to display the artist name of tracks.
+* Plugged an upload security hole.
+* Pressing the previous track button on the first track in the play queue when
+  "repeat all" is turned on now plays the last track in the play queue.
+* The volume widget no longer goes higher than 100%.
+* Changing the volume now shows up on other clients.
+* The volume keyboard shortcuts now work in Firefox.
+* Ensured that no-cache headers are set for the stream.
+* Fixed an issue in the Web UI where the current track was sometimes not 
+  displayed.
+
+Thanks to Josh Wolfe, who worked to fix some issues around deleting library
+items, ensuring that deleting library items removes them from the play queue, 
+and that the play queue correctly reacts to deleted library entries.
+
+In addition, he worked to:
+
+* Convert Groove Basin to not use MPD.
+* fix multiselect shiftIds.
+* fix shift click going up in the queue. 
+.. What does this mean?
+

+Getting Started
+===============
+
+Welcome to Groove Basin! This guide will help you begin using it to listen to music.
+
+Installing
+----------
+
+Installing on Ubuntu
+^^^^^^^^^^^^^^^^^^^^
+
+Groove Basin is still in development and has not yet been packaged by Ubuntu, so you will have to build it from source.
+
+Install `Node.js`_ v0.10.x or greater. We recommend using `Chris Lea's PPA`_ for Node. If you want to use the PPA, run:
+
+  ``add-apt-repository ppa:chris-lea/node.js``
+
+  ``apt-get update && apt-get install nodejs``
+
+.. _Node.js: http://nodejs.org
+.. _Chris Lea's PPA: https://launchpad.net/~chris-lea/+archive/node.js/
+
+Install `libgroove`_ from the `libgroove PPA`_:
+
+.. _libgroove: https://github.com/andrewrk/libgroove
+.. _libgroove PPA: https://launchpad.net/~andrewrk/+archive/libgroove
+
+  ``apt-add-repository ppa:andrewrk/libgroove``
+
+  ``apt-get update && apt-get install libgroove-dev libgrooveplayer-dev libgrooveloudness-dev libgroovefingerprinter-dev``
+
+Install `Git`_ if it is not already installed:
+
+  ``apt-get install git``
+
+.. _Git: http://git-scm.com/
+
+Clone the Groove Basin git repository somewhere:
+
+  ``git clone https://github.com/andrewrk/groovebasin.git``
+
+Build Groove Basin:
+
+  ``cd groovebasin``
+
+  ``npm run build``
+
+Running Groove Basin
+--------------------
+
+To start Groove Basin:
+
+  ``npm start``
+
+Importing Your Library
+----------------------
+
+Groove Basin currently supports a single music library folder. Open the ``config.js`` file that Groove Basin creates on first run and edit the ``musicDirectory`` key to point to your music directory.
+
+Playing Your Music
+------------------
+
+Now that you have Groove Basin set up and indexing your music, you can start playing your music!
+
+Open your favorite web browser and point it to:
+
+        http://localhost:16242
+
+You should now see Groove Basin and can add songs to the play queue for playback. Double click on a song to play it.

-# Groove Basin
-
-No-nonsense music client and server for your home or office.
-
-Run it on a server connected to your main speakers. Guests can connect with
-their laptops, tablets, and phones, and play and share music.
-
-Depends on [mpd](http://musicpd.org) version 0.17+ for the backend. Some might
-call this project an mpd client. (Note, version 0.17 is only available from
-source as of writing this; see below instructions regarding mpd installation.)
-
-Live demo: [groovebasin.com](http://groovebasin.com/)
-
-## Features
-
-* Lightning-fast, responsive UI. You can hardly tell that the music server is
-  on another computer.
-
-* Dynamic playlist mode which automatically queues random songs, favoring
-  songs that have not been played recently.
-
-* Drag and drop upload. Drag and drop playlist editing. Rich keyboard
-  shortcuts.
-
-* Streaming support. You can listen to your music library - or share it with
-  your friends - even when you are not physically near your home speakers.
-
-* Last.fm scrobbling.
-
-## Get Started
-
-Make sure you have [Node](http://nodejs.org) and [npm](http://npmjs.org)
-installed and [mpd](http://musicpd.org) version 0.17+ (see below) running,
-then:
-
-```
-$ npm install groovebasin
-$ npm start groovebasin
-```
-
-At this point, Groove Basin will issue warnings telling you what to do next.
-

-![Last.fm Scrobbling](http://www.superjoesoftware.com/temp/groove-basin-0.0.4-lastfm.png)
-
-## Mpd
-
-Groove Basin depends on [mpd](http://musicpd.org) version 0.17+.
-
-To compile from source, start here
-
-```
-$ git clone git://git.musicpd.org/master/mpd.git
-```
-
-and follow mpd's instructions from there.
-
-### Configuration
-
-* `default_permissions` - Recommended to remove `admin` so that anonymous
-  users can't do nefarious things.
-
-* `password` - Recommended to add a password for yourself to give yourself `admin` permissions.
-
-   * `read` - allows reading the library, current playlist, and playback status.
-
-   * `add` - allows adding songs, loading playlists, and uploading songs. 
-
-   * `control` - allows controlling playback state and manipulating playlists.
-
-   * `admin` - allows updating the db, killing mpd, deleting songs from the
-     library, and updating song tags.
-
-* `audio_output` - Uncomment the "httpd" one and configure the port to enable
-  streaming. Recommended "vorbis" encoder for better browser support.
-
-* `sticker_file` - Groove Basin will not run without one set.
-
-* `gapless_mp3_playback` - "yes" recommended. <3 gapless playback.
-
-* `volume_normalization` - "yes" recommended. Replaygain scanners are not
-  implemented for all the formats that can be played back. Volume normalization
-  works on all formats.
-
-* `max_command_list_size` - "16384" recommended. You do not want mpd crashing
-  when you try to remove a ton of songs from the playlist at once.
-
-* `auto_update` - "yes" recommended. Required for uploaded songs to show up
-  in your library.
-
-## Configuring Groove Basin
-
-See http://npmjs.org/doc/config.html#Per-Package-Config-Settings
-
-See the "config" section of `package.json` for configuration options and
-defaults.
-
-Example:
-
-```
-$ npm config set groovebasin:mpd_conf ~/.mpd/mpd.conf
-$ npm config set groovebasin:port 80
-$ npm -g --groovebasin:port 80 start groovebasin
-```
-
-## Developing
-
-Install dependencies and run mpd as described in the Get Started section.
-Then, from a clean clone of the source repository:
-
-```
-$ npm run-script dev --groovebasin:development_mode true
-```
-
