This is the laziest way of doing it IMO. You can't just upload a track to soundcloud and expect it to blow up organically, you have to promote it heavily.it seems like cats don't grind anymore b, they just drop a song on the cloud, waiting for it to blow up.
The dude who really laid down the blueprint was Soulja Boy.
he built up a following from youtube, facebook, twitter, instagram, myspace, tumblr, etc....he utilized all of the social media platforms to become a "thing".
The fact he's still mentioned now when many would of claimed him to be a one hit wonder is actually pretty damn remarkable and I can tell he still got Crank that money
