Hacked hack

Hello,

Here's the changes I made to Matt's Echonest fork, in case you want to merge anything back. You probably won't want [all if any of] the readme.

Demo here: http://hugovk.github.com/now-playing-radiator/

Main changes from Matt's fork:

 * Added album art to main view and favicon
 * Added links to Last.fm's artist, track and album
 * Added link to lyrics on lyrics.wikia.com

Cheers!
