Fresh, free music with Sonic Router

I recently came across Sonic Router which have a nice collection of dubstep/electronic/hip-hop mixes from various artists. One of my favourites so far is by Lapalux.

Bored of opening the Sonic Router homepage, finding the list of mixes, choosing a random one, hitting play, I knocked up a little Ruby script that opens a random one in your browser. And if you have dotjs installed there's a little snippet that will autoplay too.
