This web app lets you upload a favorite MP3 and will then generate a never-ending and ever changing version of the song. Infinite Jukebox uses the Echo Nest analyzer to break the song into beats. It plays the song beat by beat, but at every beat there's a chance that it will jump to a different part of song that happens to sound very similar to the current beat. For beat similarity the uses pitch, timbre, loudness, duration and the position of the beat within a bar. There's a nifty visualization that shows all the possible transitions that can occur at any beat. Built at Music Hack Day Boston 2012.
