I just discovered Regina Spektor and have been listening to her a lot lately. Her song "FIdelity" is what first got me hooked, but her other stuff is fabulous too.

You can listen to everything she's recorded in it's entirity (as opposed to little snippets) on her website if anyone wants to check it out. http://www.reginaspektor.com/

Also, I'm going to a Carbon Leaf concert tommorrow which I'm PSYCHED about!
