I grew up calling it either Elevator Music or Muzak, so it might be a regional thing.
It used to be always 'easy listening' instrumental versions of the popular songs of my parents' generation. I think a group called "101 Strings" were typical of that.
Now I hear a lot of vocal music, pop cuts from the artists in the Baby Boomer generation and beyond played as 'overhead' music. Times change.
I'd love to hear my music in an elevator, as long as I was getting royalties. Ka-Ching
