GodWanna by Everlast. If you really want to feel the bass, get this song. Unless you got some nice speakers, you comp will not do it justice.
Space Lord by Monster Magnet, another classic
Tall Cans by Afroman, great bass
Stupify by Disturbed has blown out 4 pairs of my headphones
Wasting Time by Kid Rock, great bass, great feel, great song to smoke weed to
When the Levee Breaks by Led Zeppelin, kind of repetitive but good solid bass throughout
Heart of Gold by Neil Young, very chill
Sleep now in the Fire by Rage Against the Machine, great song to get pumped
One of These Days by Pink Floyd, kind of wierd, but great song to listen to
Today by The Smashing Pumkins, another great song to get pumped
Rocky Mountain Way by Joe Walsh, classic
By The Way by The Red Hot Chili Peppers, flea is amazing. nuff said
That just about wraps it up. If you really want to feel it, though, listen to GodWanna. Trust me.
