Yes You sure can. When you buy the loop and customize it or use clips from the one You purchased in your own work, then that is it. You would then own that as your mix and can Go Ahead and be as successful as You like with the finished product! Once you buy the loop and alter it to a certain extent, you would own the rights to that work. If it gets chosen for radio, Television, or internet play You would be All Set! Feel free to let us know as we take pride in Your successes and let others know where You got Your loops from!
