Disney have released a 6-minute compilation of clips from across the soundtrack. (including stuff I've not heard before)

There's quite a mix of orchestral pieces and electronic music (some quite 80s sounding, and some pretty awesome sounding)

The website isn't loading very well, so let me know if you'd like the mp3.
