Wow...I can't believe I didn't run up on this thread sooner...I just read through it and everybody got some great picks, some of those soundtracks took me back. Here are some I didn't see.
The Wackness...mid 90s hip-hop scene in NYC, come on now
Shaft...the original, Isaac Hayes is a beast
Krush Groove...Run DMC, the Fat Boys, Shelia E, Kurtis Blow, you name it, the best of 80s hip hop layed it down
Wild Style...any rap legend not on Krush Groove was on there
Menace II Society...west coast at it's finest
High Fidelity...if you love vinyl, you love the soundtrack, it had some dopeness
God is a DJ
