I would be VERy careful especially if you have hot shit....especially with good melodies and concepts, that shit is rampant nowadays especially producers that done already made the cut, that need ideas like melodies or overall dope shit....but oh well thats how it goes though....as usual copyright, blah, blah like i've been preaching since day one, but there is some catches to that too.....like by the time you have gone through all of the legalities to prove someone stole your shit many times everyone involved in the project has gotten their cuts off of it and its hard to fight that.....anyhow just a caution on submitting tracks as opposed getting meetings and playing your joints.....
