I actually worked in a grocery store (in the deli) a little over a decade ago, and the music over the PA was literally a 5-CD changer that the owner stocked with some pop music CDs. The two summers I was there taught me, beyond anything else, that I really hate Eric Clapton's "Forever Man" and Minnie Riperton's "Lovin' You."

Also that head cheese tastes exactly like spiced fat.
