Features

• Playlists - Dynamically create playlists.
• Sorting - Sort playlists by Title, Artist, Album, Genre, etc.
• Searching - Seach Seeqpod for mp3s available online. Create playlists of music from search results. Get album art on the fly from Flickr API.
• Navigating - Navigate playlists with arrow keys like in iTunes and other desktop applications. Follows iTunes' other shortcut conventions: Ctrl+Up/Down = Volume Up/Down, Ctrl+Left/Right = Previous/Next Track, etc.
• Streaming - You don't have to wait for mp3s to load before playing them.
• Visualizing - Real-time visualizer. (Note: Only works with locally hosted files, all other mp3s use random visualization)
• iTunes-like UI - Very fluid layout which is familiar to millions and very easy to use.

Known Issues (report any here)

• Visualizer Doesn't Work When Youtube Video (Or Other Flash Video with Sound) Is Open In Another Browser Tab (see areSoundsInaccessible() method for flash 9.0)
• Library Persitence only in Firefox
• Delete Track While In Playlist Removes Highlighting of Currently Playing Track (issue is with Playlist().current)
• Shift Select Playlists, then Press Up/Down Arrows
• Many Features Broken in Opera
• Track Shouldn't Be Allowed To Be Added to the Same Places Twice Resolved in v1.1
• Up/Down arrows and Delete button don't do anything in Internet Explorer and Google Chrome. (See megaKeyboardHandler(). Anybody know what I'm doing wrong?) Fixed in v0.9 (simply needed to bind keydown to document instead of body)
• Specific Aesthetic bugs in IE. Fixed in v0.6
• No title bars (and therefore no sorting) in Google Chrome. Fixed in v0.5
• Pages have wierd scroll bar issues. Fixed in v0.2
• Building Playlists of length >100 Tracks can be slow (and hang the javascript interpreter). Fixed in v0.2 (Playlist.add() unnecessarilly redrawing the playlist table)

Embedding worldTunes interface with your own Library

• Simply place an iframe on your webpage with the src as http://polymath.mit.edu/projects/worldTunes/#/[LIBRARY JSON], where [LIBRARY JSON] is JSON code representing the library of tracks you want the player to be initialized with. For example, you could use the following for string for [LIBRARY JSON]:
• 
  {tracks:[{title:"Intro",artist:"Adam Schwartz",length:"0:19",url:"/www/music/21.mp3"},{title:"Black Part I",artist:"Adam Schwartz",length:"8:51",url:"/www/music/22.mp3"},{title:"Black Part II",artist:"Adam Schwartz",length:"4:26",url:"/www/music/23.mp3"},{title:"White Part I",artist:"Adam Schwartz",length:"16:17",url:"/www/music/24.mp3"},{title:"White Part II",artist:"Adam Schwartz",length:"6:08",url:"/www/music/25.mp3"},{title:"Black & White",artist:"Adam Schwartz",length:"8:02",url:"/www/music/26.mp3"}]}

That would give you the example found here.
