One of my currently favourite toys is Infinite Jukebox by the people at the Echo Nest. The Echo Nest is a spin-off from research done at MIT Media Lab. They analyse music and music contextual data and make programs and intelligent services based on that.

The Infinite Jukebox is a simple, but brilliant example of this. You can upload an mp3, their tool analyses the song, finds the beats and notes the similarities on those beats, which are essentially ‘skip points’. Once you press play, the song will play and seamlessly skip back and forth through the song on those skip points, creating an infinite length version of your favourite song. In case you hadn’t heard Gangnam Style enough yet.

More on the workings of the Infinite Jukebox on Paul Lamare’s blog. Note: it does require Google Chrome or Safari to work.
