If you want to go for it.
Personally I like to listen to this when I'm doing a battle situation: http://www.youtube.com/watch?v=46tS09yBc9I
I usually listen to some sort of sound track mix when I work with projects that need a more artistic flare. It distracts part of me and lets me focus. But anyways, If you guys want to, then go for it. Might be pretty cool to listen to your opponents music of choice or even put your own in when you are doing this.
