Music Babble

I was at a chamber music concert the other day and they played a piece called "100 Greatest Dance Hits" with the following movement titles...

Introduction
Salsa Pasada
MOR * Easy-Listening Slow Dance Ballad
Dance Party on the Disco Motorboat

The cellist introducing it pronounced the third movement title as "MORE Easy-Listening..." Gen Z does not know the old radio programming term "MOR"! I explained it to him afterwards and he was shocked. Never heard the term before.
