Eric Wahlforss of SoundCloud released “The Cloud Player“, an open-source a iTunes / Songbird-clone built in jquery (and app engine, soundmanager 2, soundcloud api), complete with smart playlists, drag’n'drop, keyboard shortcuts, load-as-you-scroll playlists, playlist sharing, waveform display of tracks, etc. It’s using soundcloud.com as the primary music source, and the SoundCloud JSONP API to access the track metadata, available at http://soundcloud.com/api.
