> One of the local grocery stores here will play a bunch of 80s hits. They play Eye of the Tiger regularly. That song is one of the most purpose driven songs ever. If you had a mission to pick up 7 items in your list you can be sure you'll be done in record time.
As somebody who likes to finish their grocery shopping quickly, I picture myself in a video montage with that song as the soundtrack.
Sidenote: I felt old when I heard Gangsta's Paradise being played in a grocery store about 10 years ago.
