I hear you....
Take a trip out there once in a while.....go to a few shows with product in hand with contact info......
I sold 4 beats on the strength of a live beat battle, not the internet. I'm not bragging or anything.....but none of those beats were on the net to share..
I actually have the tracks I put on my myspace mainly for people back in NY I know. There's a shitload of tracks I've done better that I wouldn't put up because there's a lot of grimey people out there....and don't think for one second putting your tags is going to protect you...I've seen my boy literally take them out of one of my beats............So if someone really wants your shit, they will take it.....
