justin timberlake - bastard

(back to what does help - i find any sort of rock music... the faster the better i suppose so homebound train anything by iron maiden, some deep purple stuff, a lot of Rainbow stuff, or some Sabbath/DIO music - donnington 87 rocks particularly hard)... what else:

scorps - tokyo tapes
whitesnake - live tokyo 88
springsteen oddly enough (acoustic stuff - i've done that)
my own 65 min prog rock album "reflections"

MSG are good too - i should put them on minidisc

but that being said i don't intend to do more than maybe 1 hour on the running machines and music's not as important for the other machines so it doesn't matter to have a big compilation
