few more: Change Up-Fabolous ft. Akon (really low bass hit. Gotta be around 25hz)
Wood Grain Wheel- Slim Thug (29/30hz?)
Beatin Down Your Block-DJ Unk- (Series of low bass drops that go right down to the subsonic frequencies)
Crack Muzik- Gorilla Zoe (I'd have to listen to the song a few more times to guess the frequencies, but i'd guess high 20's/low 30's)
Suicide Doors-David Banner (again, can't guess the frequencies right now, but it's pretty low)
Lullaby-A Perfect Circle (probably high 20's. Good song to listen to when you're stoned
)
If you're just looking at this thread: these are my "honorable mention" songs I think everyone should have:
Sugga Cooker-DC Yung Hot (29hz)
For The Love Of Money-Willie the Kid (24hz)
Strip Club-Young Buck (27hz. Sounds better if you have more/bigger subs)
