I guess this must be fairly popular because I hear it on local alternative radio stations occasionally. Be damned if I know who sings it though. It's a woman singing with a nonchalant hard-to-describe rythmn in her voice; she finishes off her verses by singing something like "do-da-do-do-do-da-do-do-da-da-do-do". Sounds like something you might hear in a coffee house.
