How important is the vocal/s in a song to you? I mean, we all have singers who gets by because of their amazing personalities, but without having a great voice. Sometimes having charisma is enough to carry a song, but in some genres a strong vocal is necessary (for example in opera, you can't sing opera unless you have a fairly strong vocal). Personally I'm in love with Jones, but I'll admit that she doesn't have the strongest voice, but she compensates that by having an amazing personality.
