You go to any piano bar, etc, a lot of 70’s and 80’s music is the preferred music of Millenials.
I was in one of these new Taco Bells the other day where they’ve styled it to be sort of hipster trendy. Lots of college kids sitting around and what struck me was the music was all old stuff. No doubt Taco Bell focused grouped the music selection to appeal to a younger crowd, and apparently that’s what they found was acceptable to them.
