I just wanted to make this topic about this singer and song writer.
Honestly, I think she has a great talent mixing the R&B/Blues/Soul with Jazz and made a completely different genre. Personally I like those genres, very smooth and soulful. I think she's a genius song writer that's completely wasting her talent on drugs and alcohol. I suppose if you're a genius, it makes you more susceptible to being a bit crazy. However, she's going over the top crazy, she's being affected by the publicity and probably other things I don't know what's going on in her life.
I didn't care for the lyrics in the song, "Rehab" but I love her voice and the tune of that song.
