It's not always about the voice though - if you don't care for that type of music, the best voice in the world isn't going to save it.
I feel the same about Mary J. Blige, who I think has an incredible voice. Dubbed "The Queen of Hip Hop", and "Queen of Soul/R&B", she's never going to make it into my record collection. Be nice if she moved into another genre, say rock - the version of U2's "One" with her doing guest vocals is so much better than the one with just Bono.
