To answer the original question - no.
Not a value judgment, just a life reality. I stopped spending energy on pop musics in the '60s. Because of my job running record stores from the late '60s to the mid '70s, a bunch of info was gained by osmosis, but otherwise I am blissfully free of the "popular world".
I am not bright enough to absorb all I would need from tv series, movies, pop music, world music, literature, art, dance, etc. to sound smart. I also needed a huge chunk of time/energy to try earning a living, raise my kids and still need more time for my "long-suffering" wife.
In my early twenties I thought I was "hot shit" in many of these fields, but as I entered my late twenties I consciously cut back.
I post this to give hope to list members feeling "out of place" in some of the discussions on the board. Just "dabble a bit" to make sure you are not "short changing" yourself. There's a bunch of info available on this board.
