@Sbeekeht is actually right and wrong. Tagging helps BUT as he said if they’re smart they just cut around the tags (a little harder to do if you strategically place your tags). Also copywriting them won’t help either. I mean sure you got your beat(s) registered but its not going to stop anyone ripping them offline.
How much registered music do you have currently in your iTunes that you didn’t pay for? hmmm. Anyone sue you yet? Nah!
You just have to really get to the point where you just stop worrying about people stealing your beats and just say fuck it and start uploading.
If they get stolen (which they will, as do mine. Lol) then enjoy the free promo and if the song blows up then enjoy collecting all the revenue it has generated.
This is the internet man, once something is uploaded to the public its anyones game and anything can be stolen once online.
Roll with the punches and just make great music.
