People have been discussing about it since Rihanna released
Good Girl Gone Bad and became a global star... So the question is: Who had the more successful SOLO career (so far)? Please, don't be based and choose not the one that you like more but actually think about their achievments (sales, awards, critic acclaim...). Since Beyonce started in 1997 and Rihanna in 2005, i decided to exclude DC success but that also means that Rihanna's features won't be counted too. Vote only based on SOLO careers.
