Is this a weird reason to cry?

I've been wanting to know this. For many years, (almost my whole life) whenever I hear soft music such as music boxes, music played by church bells, and some church hymns, it makes me cry because it reminds me of death of my parents and grandparents. However, both my parents and grandparents are still alive and I talk to them everyday. Why does this soft music make me cry and think of death? I need to resolve this problem as soon as possible because I know I can never live with myself hearing that kind of music when they do actually die years from now. Anyone else feel the same way?
