Seriously though, it must be a southern thing because my mp3 player (iPods didn't exist when I bought it) has a lot of the same stuff Apus^2 mentioned. I only use it for riding the trainer, or warming up for a TT, so go figure.
It's mostly filled with stuff like the Chemical Brothers, Orbital, Moby, Prodigy, etc. But with the addition of George Clinton, some other funkadelic stuff, a bit of early rap (grandmaster flash era), and a few things "from the 80s" (I swear to god "Suzie Q" is on my mp3 player, yeah I should just shoot myself now. But hey, it's my workout play list, not yours, and if it helps me get done quicker so be it).
