I have the hardest time trying to understand what's wrong with 50. Most rappers start to tank later in their career, that's a given, but 50's story is just different. It's like he believes he's still as good as he once was if not better.

His entire aesthetic now is really washed up and corny, not to mention really transparent. The OP is right, 50 would rather talk about anything except himself or his own music these days because it evidently can't speak for itself.
I don't think it's a problem one or two songs could fix either, hell, let alone an entire solid album (which
Animal Ambition unfortunately will not be); 50's problem is what's starting to happen to Ross now and what Wayne started going through not too long ago:
he's running out of shyt to say.
