What Is That I Hear? Free Music?

Free Music? What? Is that possible?

Well, here are two sites that will show you:
Yes Virginia, free music does exist.

Radio Blog Club: Enter an artist or song and enjoy people's radio blogs (be sure to un-check the crossfade option to listen to the full songs).

Pandora: Listen to artists you might not have heard before based on an artist or song that you search for.

Both of the above sites don't require you to install anything which is quite nice.
