I just started riding my bike again, and for some reason I really enjoy some electronica music. Such as: Chromeo Justice Cut Copy Boys Noize Daft Punk ...and of course, you gotta go with the Nike+ albums. They only have a few out so far, but they're all amazing. It's artists that compile these long mixes especially for runners. Currently, they have A-Trak (Kanye West's tour DJ), The Hives, Aesop Rock, The Crystal Method, and Cassius. Hit me up if you can't find them online.
Soil, both Scars and Redefine. Also the new Drowning pool CD with the singer that was in Soil for those two albums. Badass.
