Breh, I know this. Let me clarify, I was a Curren$y fan back when Aint No Mixtape dropped in the blog era. However he raps fukking lazy sometimes and sounds unmotivated. As you said he chooses when he really wants to rap and be clever and I would hope a producer like JD could have him focused and wanting to really rap. On Pilot Talk 1 or even when he signed with Warner and did Stoned Immaculate you can tell he was really putting effort in his writing and trying new things. Same with most the work he did when signed with Dame Dash or the work he did with Wayne on Young Money Dedication.
All in all, I would hope JD working with him could get him wanting to really rap again like he did back in 2010 or at least trying to be creative. That's why I had to stop listening to his music for years cause it became the same ol shyt.
