The Infinite Jukebox (labs.echonest.com)

It's a bit entertaining to listen to a song backwards beat-wise. (Click play, hit the left arrow key twice, click at the end of the song.)

On Chromium 25, it wouldn't load, so I checked the console and saw "Uncaught Error: SYNTAX_ERR: DOM Exception 12 jremix.js:28".

Small UX nitpick: The fact that the 'recent uploads' had a regular text mouseover image led to me wondering for a couple of seconds whether something should happen if I click. Did it anyway, I've been jamming for a while. It wonder if how the HN demographic maps to genre popularity.

Its a little shaky, and takes a bit to load, but this is truly incredible.

Does anyone know of a downloadable program that can do this?
