If you are serous about music business and worrying about licensing and ect I would register all my equipment, Its cool to have pirate software but at one point in time in anyone life, you just have to invest in yourself! pay for everything make sure everything is legit! I have every piece of software and controllers and ect all registered! Now you don't have to do this to make money of music but, if you are serious than i would just go legit and invest in yourself properly this way you don't have to worry!
As for downloading content, Thats a war no one can win!! You can lock it, you can track it but if I want it i can get it and scrape anything off the web! If someone steals it, take it as a compliment and contact them!! Also get a writers and publishing as well! my music i chose to make money from or summit all gets registered by ascap or bmi and ect. I like ascap because they pay good and they pay period lol!om
Any beats i submit to people or placement they are sent out for mastering and than registered to ascap! this way you get paid if someone uses your music!! This wont stop from others downloaded it but at least you can make money and be protected if it goes mainstream or if the artist blows up!
hope it all works out for you and keep up the good work!
