I think Rihanna's a really bad example. She released A Girl Like Me eight months after Music Of The Sun, and then Good Girl Gone Bad fourteen months later. /

She really rushed A Girl Like Me, which probably explains why it's so rubbish.

I'm still waiting for Samantha Mumba to release an album, it's been eight years. She claims to be working with Michael Jackson and Timbaland. Oh and the new Mickey Modelle remix of Gotta Tell You is really good~
