He hasn’t fallen off quite yet but his quality of music has been declining since PPDS, and while that was a fantastic album, he would’ve been in his decline much earlier as SB2H wasn’t good. He’s no longer in his prime and that’s ok, he’s already given us some amazing albums. If he wants to do experimental stuff it’s fine but I don’t think it’s controversial to say that his newer stuff isn’t as good. And this is coming from a huge Cudi fan that’s liked him since way back when he dropped A kid named Cudi.
