Megadeth and Metallica can keep me pumped up for hours after breif periods of listening to them.
I suppose having your team listening to modivating music for a straight half hour right before start may have them pumped and ready to go with more enthusiasm then normal, but while you are playing, you can not hear anyone creeping up on you, plus the music may sidetrack you if you are like me and get sucked into the song.
I too am a musician, or what I like to call one
