Psh.... "In my day...."Get a list of the standard pieces of music you "should know."Then you need to know the composer's full name, correct spelling, birth and death dates. Date of composition. Full name of the composition, in the original language…
17,000 songs in your library? That is the problem. Delete all but 50 of three distinct composers, and then you will have no problems knowing your library. Otherwise, don’t sweat it; there will not be a quiz
It actually doesn't bother me that I don't know the all the music in my library that well. I was just curious. At least I'll always have something new to listen to. I'd did occur to me recently though that I spend way too much on CDs. Virtually everything in my library I imported from CDs.
My question is; who decides what you "should know"?
The world of music. It's the pieces that still survive over time. The same ones still programmed at concerts. The ones that will keep popping up in music history/appreciation texts.
You surprise me Bob, "shoulds" and "ought tos" do not exist for me, and I assert they have no place in art of any sort. I know you have had a much more extensive musical education than I, but I find it hard to imagine your taking any notice of fame or academia in deciding what you like, turning your rightful personal taste over to somebody else to arbitrate. That would be altogether too hideous a prospect for me.
