For me too. The headline question however was not "Is playing music good for people?", but "Is playing music good for the brain?"

That's not nearly as easy to answer.

If we're talking about long-term benefits, I certainly can't answer that, but I can say all of my interactions with music have been positive from merely listening, learning to play several instruments, learning music theory, etc. Music has been one of the great joys of my life.
