Jim, you seem to be very much into Perry Como of late.
Back in the period just prior to my interest in jazz, I was a Perry Como fan. Always thought he was one of the very best singers of popular music. No affectations, just straight ahead singing.
A piece of visual art may be placed on the wall of your home. You can view it every time you walk by it, or sit in the room where it is located. Of course it may just become part of the room, just like a piece of furniture, and you pay little attention to it.
One does not play a recording of a piece of 20th century classical music over and over all day long day after day so it it becomes part of the regular ambiance as is done with a piece of visual art.
I think that TTK makes a very salient point. Seeing a painting or sculpture by a 20th Century artist may require repeated viewing to gain greater, or any, appreciation. One can sit in front of a piece of visual art for a few minutes at a time, and view a photo in a book or magazine.
Listening to a piece of 20th Century "classical" music may require a far more extended time committment in a concert venue or on a recording.
There is also a financial aspect. Many museums are free or the cost quite modest. Attending a concert or purchasing a recrding is more expensive.
