The quest to find good songs to perform often prevents me from enjoying other music simply because it doesn't fit in with my criteria. I've overlooked some great songs in the past by listening too hard for something else!
I find I only truly enjoy listening when the music is just "on" and I'm otherwise engaged.
It can also be a problem when I go to see other performers, much to the annoyance of my partner who isn't remotely interested in what equipment is involved, what tunings are employed, or what my opinion of the sound technicians is!
I think she has more fun than me too!
I am trying to learn to "switch off" long enough to have a good time but it's one day at a time!!
