I wasn't sure how my XM radio experience would go, but since I started listening to the channel BPM its been a pretty good experience. With DJ's and mixes both new and old, I think bpm.xmradio.com BPM is pretty sweet. My current favorites.

Ferry Corsten - Watch Out
David Guetta - Love don't let me go
Watch the Sunrise - Axwell and Steve Edwards
Moonlight Party - Fonzerelli
Fast Cars - Hellbent
Sexy back - Armen Van Helden Remix
Benassi Brothers - Castaway
Nadia Ali - Rapture
Bob Sinclair - World Hold On
