I'm 47 and still attend the Bonnaroo Music Festival every year and go to about 20 concerts annually here in Nashville.
I'm too old to listen to much pop music but there's still good music out there.

It does get harder and harder to find original music as your ears get older and more experienced.

Of course I've had to get used to being that "old guy" at a lot of concerts but what do I care what college kids think of me anyway.
But Bonnaroo has lots of old folks and there is a small but dedicated bunch of oldsters still going to shows around here.
