@Dotcom said, in any other art form, not writing your own shyt is unacceptable.
As a producer myself, if my beats/tracks weren't made by me and I had reached a certain level of fame...and somebody found out and I was exposed that would be the end of my career. Basically, I would be just a figure behind music while someone else made it. And I had NOTHING to do with it other than put a face to it.
So why should it fly in hip-hop? It shouldn't.
I just wish I had heard of Quentin Miller without this....he has great music. But it frustrates me knowing that this industry really doesn't push genuine talent like that but what is "marketable".
