Cheapo Music - Free and Downloadable
Use any or all of these streaming Internet radio stations:
Grooveshark
Pandora
Slacker
To download any audio from the Internet, use OpD2d - direct to disk audio recorder. It supports the MP3 format, but you have to use this little trick.
I also get songs and support bands in the Live Music Archive. Kudos to Dark Star Orchestra and Cornmeal for giving us so much joyful noise!
You can also get music off of My Space by following the video tutorial below.
