Any Aimee Mann fans? She did most of the soundtrack for Magnolia back in the day, and even further back was in Til Tuesday. She's also had some small roles in movies and TV. "Voices Carry" was probably her biggest hit. "Save Me" off of Magnolia also did well.
I asked her about doing soundtracks, and The Big Lebowski and some other stuff here:
