I fully disclose that I'm somewhat sleep deprived today. For all I know, I could be totally off on this.
Music is
a. a destination
b. a journey
It would seem in my mind that most debates are people who view music as a destination vs. those who view it as a journey. For example, covers vs. originals. Music as a destination: This IS it. Music as a journey: Is this it?
Its fun to do, it feeds your brain, keeps those neurons popping. Its becoming more evident that musiciians that continue to play into there elderly years are less likely to have dementia or alzheimers. So yeah, its good for you. Probably didnt answer your question though, but probably more to the journey side.
I love your quote lfmn16, it pretty much sums up what you just said. I'm more of a journey. I like answers from many people, and using that as part of the equation I come up with my own.
