I'm UNREΛL, I make free of rights music, take a listen on my soundcloud. I propose a variety of songs on many selling platforms for people to use it on their project, just check out my website for all the links or if you want to contact me for hiring.
You pay only once for the rights to use it in a video-game project, advertising, youtube video or whatever you want, without fees for every listening. Basically, you don't have to pay more if you sell zillions of copies of your game. Makes things easier.
