Can't Beat Free

Classic Cat is a nice catalog of freely available classical music. Songs are listed by composer and performer. I've never heard of any of the performers, but I'm pretty ignorant. The sound quality of the songs I picked up sounded good to me, but I'm one of those guys who can't tell the difference between a $300 home theater in a box and a $10,000 stereo.
