The music industry today is seriously failing if they can let Katy " Tone deaf" Perry get that many no.1s. Her and Rihanna. Adele Gaga and Bey don't need all those number ones. I think they would rather be remembered as artists with actually talent that sells albums. They are not selling albums, even though no one really is nowdays but how can you get all those hits and cannot sell. People don't won't her album they just want to spend 1.29 on her. And Katy Perry does sell sex. I mean look at her Cd cover, she's naked. Are some people blind? She has whip cream coming from her breast.
