Wayne has not been great other than some good songs on No Ceilings you are right on that for sure. I think thats what happens when (a) he could just record him farting and it would get heavy radio rotation and (b) his strategy has always been to over saturated the market with music so that he stays current and it isn't always quality. He's just proof that no matter how good an artist is a lot of songs/music just won't make the cut when you are a big name.
I enjoy Drake, he isn't my favorite but I take it for what it is and that is pop RnB/rap. I've listened to TML briefly, and wasn't overly impressed the first time through, right now I like his mixtapes better.
