To me, she lacks passion.
@unreceivedogma I think you are onto something. For those of us from classical music based musical cultures, her songs are verbal narratives without a corresponding musical conflict, or resolution. The music is more mood than drama.
I think that's what's missing for me. Entire mood albums, and, rightly or wrongly, I keep expecting a musical piece with a point, counterpoint, and resolution, much along the lines of a classical piece and nowhere on the album does one appear.
