Again, been a few years. I don't know much of Jeezy's stuff outside about three tracks (Standing Ovation, Soul Survivor, 24-23). I just know almost all of Nelly's tracks pound. Pimp Juice was my showoff track for a long time.
And yeah, producers would be easier but it's hard to search for producers on iTunes or in the music store.
Y'know if this thread wasn't 200 pages I'd be tempted to consolidate at least all of the rap suggestions into one post. I skipped around randomly and kept seeing a couple tracks over and over and over again.
