That's kind of a tone-deaf question. The person died and all that you are wondering if they had an unused music for some reason. What does this has to do with you anyway? I, for one, am think its none of your business.
People live on through their work and it's a honour to listen to what they did as they were remarkable. I was almost upset by your comment but I've read your other posts you sent others and I can see that you are a troll.
