...he should take time out before writing and recording a new album till it's finished then go back to acting.

I think the problem with rappers turned actor is that their focus isn't on making the best music, it's become a backseat to their acting career, so the passion isn't there and they start to believe all the hype that others tell him about how great they are at making music while still acting by their acting associates/buddies who wouldn't tell them the truth anyways cause most of them only listen to pop music anyways.

With LL, he always have two or three good songs on each album since "Phenomenon" but that doesn't mean it's a good album.
