I too searched for free music on the Internet. Eventually I got to AllCoolMusic. They offered a lifetime membership for $34.95 and a two year plan for $.99 per month. The downloads would be free (and they have been). I chose the two year plan. Soon a charge showed up on my CC account for $24.95. I asked them about this. After an exchange of emails they converted my account to a lifetime account for no extra charge. I got a warm feeling.

Best of luck with your CC issuer.
