Must be your browser re directing you. It opens to the main site right away for me and asks to Sign up or browse music. Browsing the music takes you to a page with links to what would seem to be at least a hunderd artists.. all the typical stuff you find elsewhere. So far all seems straight forward and no pop ups or trying to sell you anything. So might be a clean place to post songs. I'll be giving it a try as myself I agree with their intro.
