A few examples-

Cam'ron - Wet Wipes
Diplomats - I'm ready
AZ - Royal Salute
Nas - Zone Out
Gang Starr - The Militia
Jay-Z - 1-900-Hustler
Ghostface - Run
Game - One Blood remix (has anyone else ever heard this track? It's The Game featuring like 23 other dudes! Fabolous, Jada, Styles P, Clipse, NORE, and even Ja Rule rips it, believe it or not. I guess Ja is all done with being a diva.)

There are countless other tracks I love but I mean, who cares?
