I got to know, what did you mean when you said that you're going to play some diegenic sound to prevent people from just ripping this off YouTube. I don't understand what you mean by that.,(reply>), There are websites and programs that you can put a youtube video URL into and it will let you download all the audio in a video. So you could get the song for free, so music videos have a bit halfway through the song of random sounds, like people talking in a cafe so if you want the full song properly you have to buy it
