I was thinking about this and it would be a GREAT and totally game-changing idea when comparing SG to other services.
It would be amazing to offer free beats in exchange of an email address. I mean, single beats, from the player, that, when you click on the free download button, would show you a pop-up requesting your email address, and then after you enter it, you can download the beat.
That would be a great and easier way to grow our email lists without having to use pop-ups, and in a way that could engage users a lot easier!
Tell me what do you think about it guys! (and sorry if my english is bad, i'm from Argentina) :)
