So what kind of music do you put in your playlist and why and for what reason?
Example -
Grinding - I put on a ton of Chemical Brothers and Tokyo Police Club, the quick beats keep me focused. ;P
Instance - More Hardcore, As I Lay Dieing, Norma Jean. Everythings cooler with hardcore music. =]
I also suggest www.siradio.fm. Hit miss with the DJ's but it's fun to listen in and they have some REALLY good techno and song.
