From their website: In January we're going to start the Solid Rock FREE TRACK OF THE MONTH CLUB for everyone on our email list. Each month we'll send you a link to download a free song from the Golden Age of Christian Rock! All you need to do is signup to be notified when a new song is available for download. There's no catch, you aren't required to buy anything, and best of all, we won't give, trade, or sell your address to anyone else. You're safe with us! So sign up and start listening!
