When I walk into a Trader Joe’s market, the music is always of a bygone era. One day, I’ll hear songs from the early ‘60’s, the next, songs from the mid and late ‘60’s, etc. You never hear songs from the ‘80’s, ‘90’s or 2000’s.
The same is true in other stores.
Probably to target the Boomer market that shops there and ‘enhance the experience’.
I was just in a Trader Joe’s store patronized mostly by students, and oldsters and no music was played.
