When I playing Team Fortress 2 late I like to put on Collin Murry on Radio 1. His show is from 10 to 12 and he plays some really, really weird shit.
One of his main shows is "Audio Bully" which is basically a mix of...well, everything. I don't just mean music either. For instance, you'll hear a cool remix of Arctic Monkeys Brain Storm then Family Guy with sing about the PTA, then theres the sound of David Attenbor talking to some monkeys, the Bob Dillon will be played over the top, then theres what sounds like a porn movie and so on. Its really weird, but hilarious, and surprisingly relaxing. This mix with me blowing people to liquid shit on TF2 is pretty awesome.
Oh, did I mention he played "Still Alive" from Portal the other night? It's one of the most surreal things I've ever heard on the radio, simply because it was so unlikely, and really out of context (99% of the people listening must of been thinking "WTF is this?")
