One new music source I have been playing with is magnatune.com. They sell downloadable music for independent artists.

All the music is available to listen at any time in its entirety for free via high quality streams. When you buy an album, you can download it in a variety of formats, including full uncompressed WAV files. There is no digital rights management.

You can choose from a sliding scale how much you want to pay for an album. The artist get 50% of every sale.

It is kind of the complete opposite of the RIAA. I recommend you check it out. I have found quite a few really good indepent artists this way.
