For me she is not soulful nor lovable.I said it's just me.
As for soulfulness and being lovable my standard is Michael, sorry for that, I know it's not fair.
For my taste her voice is too rough and I don't "feel" her songs.He's 21-22 but she is not convincing me when singing about love.Michael convinced me at 9 years old singing about being in love and suffering from love
But even comparing her to the other 2000 artists I can't tell she is too special.I am more into Katie Melua , not so far , 2006 I think, she was the best selling female artist in UK.For me she is soulful and lovable and made me wanna buy her CD's and live concerts.
