It wouldn't really matter to me whether or not Kesha is freed tomorrow but if that happens that'll just mean more music so I hope the truth will be revealed.
Not really. Mariah has hardcore fans because her music is relatable to many and it's personal as she writes her songs. People Iove Beyoncé because she has the whole package. Gaga attracts all the weirdos/outcasts and makes them feel special. Madonna attracts all the gays.
Katy and Rihanna are examples of pop stars who don't really have a big fan base because they don't bring anything to the table aside from their catchy hits. Most of the others do.
