I agree with some comments on here. Music business would be better if a few people dissappear, Katy Perry being one of them, obviously Rihanna too. I´m tired of models who are making their way to 30 and still have not done anything worth the hype. True greats did great things all of their careers, but if u focus on their careers before 30, they did it all musically too, at that young age, it´s called having real talent for music. If you don´t have it is impossible, or maybe you do some good things after 15 years in the business, fake good things thanks to experience and producers, nothing else
