"Daughter" by Vienna Teng from the album Waking Hour
This is one of those songs I'd never have heard were it not for Pandora. I created a Pandora station with just one artist: Tom Waits. After hearing Barcarolle from Tom's album Alice, I've been treated to some eclectic and highly enjoyable piano-based singer/songwriter stuff. Anyway, I like this Vienna Teng tune. She's definitely influenced by the likes of Nora Jones and Tori Amos, so if you like artists of that caliber, check her out.
