I’ve been making a playlist out of answers from the last question I asked—about which songs give you the chills—and it’s a heavy one. So I’m thinking something more upbeat is in order as a follow-up. Since college, the tune that put a smile on my face no matter how blue I was is “Every Day I Write the Book,” by Elvis Costello and the Attractions. When my marriage was in its final death throes, “Hey Ya” by Outkast was a big hit, and that did it too. There have been many more, but those are the ones that endure, for whatever reason. How about you?
