J. Cole is straight fire, i probably played "the warm up" as much as "so far gone" He's got a lot of buzz on the internet and a lot of hip-hop sites are co-signing him, but outside of that, the people that have given the warm up a listen, really like him.
"Who Dat" was his first single off his album and i think "Higher" is his second one. I dont really like them that much.
Whoever posted "Dreams" you'll like this track too, its off his sample for the warm up.
