Scared of being jacked is being scared of success.
Put that "I'm afraid if being robbed" idea out of your head. Because when you feel like that, your music isn't even good enough to be stolen, and by the time it is good enough to be stolen, you won't care anymore.
Trust me.
Information and links straight from the original source on my site BeatsUrban: Electronic Copyright OfficeMy beats are not registered because it would be too expensive to register a copyright for every single beat as soon as I make them. Besides most times, I create the beat then email him immediately after rendering because I want/like quick feedback. I'm not concerned with him stealing my old stuff but since I'm pushing myself to be more unique lately, I'm worried about sending him stuff in the future.
