I love her voice and piano playing.
Agreed. She's very relaxing, but not very original.She cultivated one of the most comfortable, luxurious aesthetics ever with her piano playing and seductive, smoky, quasi-jazz vocal tones and styles. That said, I haven't been too convinced by her attempts at pop or, perhaps more accurately, adult contemporary music; and artistically I think she's, at best, just tread water since her early albums. Still, she's one of those artists I can enjoy in the same way I enjoy relaxing in a hot tub. Not the most intellectually engaging experience, but it has its pleasures.
