One of the better artists you have heard but probably don't know of that well. The songs from her first album were all over the place in commercials, movies and TV shows, and they were used for a reason -- they're catchy as hell.
Her music is a mix of Prince-like funk and Lenny Kravitz rock, with a poppy icing on the top. She was Joss Stone before Joss Stone existed. do yourself a favor and check her out, and then I dare you to tell me you don't bop your head while listening.
