@Don Von Alpha Dom
I think you are misunderstanding him. He isn't using the music button on IMVU, although he is saying that this music is there to be sold on the music section.
He is trying to create a trigger product that plays 20s each of said song, and he is saying that this specific song isn't playing when he triggers it, I guess.
Neither he remixed or created the song from the ground up, as far as I can understand.
