Hey, here's the BEST site for getting music. They have a small selection, but they have the BEST service!
They have great customer service. My favorite artist I find through them is Joe Purdy whose song "Wash Away" still moves me no matter how many times I hear it. And they've also just introduced me to "Cake Bake Betty". Her CD "Songs about Teeth" is worth taking a listen to.
CD Baby...I love you!
