Get some
-PinkFloyd and listen to 'Wish you were here'
-Metallica
-S.O.A.D.
-The Doors
-Linkin Park?
Those are the artists i like, thatll keep me either either awake, or sleepy.
(Metallica, S.O.A.D., Linkin Park) = Awake
(The Doors, PinkFloyd) = Sleepy
If you get some of their cd's then thatll last ya a good 4 or 5 hours?
