Anything involving math or brute for science I go hardcore punk rock (my populations dynamics teacher this semester followed punk bands for five years and wore a Minor Threat shirt first day to class /claim):
-Bad Religion (lead singer teaches at my college and said hi to me /claim)
-And of course Slayer
If I'm writing a paper:
-Folk/rock like Bob Dylan, Johnny Cash, Arlo or Woody Guthrie
-Hypnotic Brass Ensemble (jazz helps to write)
If I'm reading or studying:
-No music. I can't focus or read when music is pumping into my brain.
