Different types of music can serve various purposes in one's life besides stirring up memories. Rock music can be used to get energized prior to a meeting or a presentation. It can also help soothe anger. Dance music definitely works for energy but more on the aerobic and happy side of things. Classical helps with relaxation and clarity. I have yet to understand the beauty of classical music but I see progress there! I think I would rather learn to play the classics on piano first. I hope after that, the understanding will surely follow.
