Just because he getting noticed, doesn't make him good does it?
Nas "LIfe is Good" is a great album, but to compare it to "Channel Orange" is stupid. Completely different genres.
As for the rappers I like, well there is to much to mention, but heres a quick rundown:
A$AP Rocky, Kanye West, Nas, Schoolboy Q, Kendrick Lamar, Big K.R.I.T, Pusha T, Waka Flocka Flame (Cant beat some trap) and Yasiin Bay (Mos Def). Of course they are many others aswell but that just a taster.
Don't like Lil Wayne (Tha Carter 2 and 3 were good though) and only like some of Drake's stuff.
