Regina Spektor is pretty good with her metaphors.
Here's a non-album track called Bartender – download mp3 via yousendit. It's certainly not my favourite of her songs – but I offer it up to those who may already own the albums.
(You don't own the albums? Get thee to thy chosen musical emporium!)
What to notice about this song? Apart from the nice metaphor, and the characteristically witty and beautifully performed 'trick-trick-trick-trick-trickle' passages ... I'd say the way that she takes a simple descending piano chord sequence and wallops a great big dischord into the middle of it.
... And yet, by the end of the song, you're utterly used to it. Clever.
