When I listen to fast heavy music, I play very aggressively and stupid.
If I listen to music from a combo vid, while playing that charactor from that combo vid, I try to play like that player from that combo vid.
Listening to slow music makes me play slow and smarter.
When I listen to techno, I SD a lot.
Generally when I listen to music, I play worse. I listen to the music, but I dont concentrate on the game.
Sometimes I sing along with whatever song I am listening too, and this distracts my opponent. (I dont do this intentionally. )
If I put my mp3 player to play random songs though, sometimes I get victories, because my playing style changes so much from whatever I am listening too.
