I should add, as supporting evidence, my experience with music.

I'm pretty sure that I'm literally musically retarded. I took lessons on several different instruments as a kid and never got anything out of it, despite quite an investment of time and effort.

For many people, as I understand it, playing music helps them think about things other than music. While I was able to play some set of recognizable songs and answer many basic music questions, it made essentially no impact on my cognition and I think that's because I never connected with it.
