Hi, Brither, and welcome aboard. My mother often had KUTE (a "beautiful music" station in Los Angeles/Glendale) on a house-wide intercom when I was in high school (the early 60s). What they played was low-dynamic orchestral versions of Sinatra type music. As I believe I noted earlier in the thread, it was music intended to be ignored. Love is Blue
is not really elevator music, either, although I might put it in a category I lovingly refer to as "couch and fireplace." Lots of artists did soft ballads from the time I started paying attention until I gave up on pop music. Even Elvis Presley did Love Me Tender
. And that wasn't recorded just to cover up the noise from the neighbor's kids.
I do have a few "beautiful music" albums in my collection, but it's not a large number. It's usually because there was some other feature of the recording, like it being quad or having a picture of a naked woman on the cover somewhere. Yes, I can be bought, sometimes quite cheaply.
