If you don't want it stolen.....don't put it on the web.
lmao i learned that when a certain rapper (who's a big name right now) had his breakout single that contained very simliar melodies and a indisputably unique line in a song i did with a friend.....who i later found made copies of a basement recording session for his own "demo cd" and handed 'em out all over, one of which ended up with that guy's manager.
I didn't sweat it cause the songs (both the rapper's and mine) sucked in my opinion (lol) but.....the theme rang true loud and clear that day.
