I agree, I meant more that he made that the single. It wasn't a single type of track, and I feel he brought the quality down because he tried to make the song to fit some single "standards". Don't know if it makes sense.
Btw, to my other point of great songs from his mixtapes getting wasted.
I just went on youtube and typed G-Unit radio, and came across songs like Like a Dog and The Mechanic (songs I don't remember, or most of his fans wouldn't even remember), imagine those type of songs on Curtis or the album after it, instead of trash like Amusement Park. He damaged his own run.
edit. o shyt didn't even realize that The Mechanic has the same beat (sample) that Kendrick used for MAAD City - I wish it was mixed better. Great track.
