My friend Mark just gave me a mix CD with a lot of his favorite female artists. It's a pretty good deal. Some of them I already liked (Rasputina, Feist), others I didn't know. The band Over the Rhine, for example, I'd only heard about from him.
Gotta say, Amy Winehouse's "Fuck Me Pumps" is a funny song. She's one of many tabloid trainwrecks in the news now, but unlike most is actually contributing something to the class.
Update: Maybe the above statement could use some illustration.
