FoldedSpace has ripped and posted a rare collection of the best music from 1901-1920s and posted it, along with commentary. These public domain songs are delightful, and feature some of my favorite artists, like Billy Murray, who sounds a little like Bugs Bunny, and even an original recording of Sousa's band. The CD version of this goes for as much as $190 on Amazon and eBay, but since the music is in the public domain, it can be freely redistributed.

ASIFA-Hollywood Animation Archive director Stephen Worth sez, "Murray actually did do cartoon voices.
He was the original voice of Bimbo in the Max Fleischer
Talkartoons, and his voice is featured in quite a few
Bouncing Ball cartoons. We have one of them posted on
the ASIFA-Hollywood Animation Archive Project Blog.
