if you see me in a fight with a bear, don't help me fool, help the bear!
Ok, I've already spelled it out, but I'll try to do it again. Bryan Cranston doesn't play himself in Breaking Bad. He plays a character. At the end of his work day, when he goes home to his wife and kids, or when he does an interview for Entertainment Weekly, he doesn't pretend that he's the psychopathic meth cook Walter White. Now Lil Wayne does rap about himself, telling stories of mostly fictitious drug deals and assaults. Now, the thing is, he also has a record to back up the assertion that he does live the life of a thug. He's been arrested for weapons and coke possessions. How is that the same as Joe Pesci or James Gandolfini, I don't know...
Rick Ross doesn't play himself also! Rick Ross isn't even his name.. so really you are saying it is ok for an actor to play a gangster but not for a rapper..
They don't tell stories about themselves or else their raps would be about waking up late, and recording in the studio.. It's telling a story just like Joe Pesci did...
