it'll take me a while to narrow it down to 10, but 5 i know that stay in rotation:
jay
ye
kast
pac
redman
...after those 5, i dont know how it breaks down to who i listen to more out of a bunch of people like nas, face, wu tang (including solo joints), lil jon, ugk, ti, rakim, tribe, big, dr dre, the liks, devin the dude, dipset (including solo joints), budden, j cole, etc. to round out a top 10.....
...another thing that is making it hard is that i tend to listen to more rnb now instead of rap....so when i want a rap fix, i tend to go to one of the 5 i mentioned first....but i'll get back to you with another 5....
