My Three Things

Anyone who lived in the D.C. area during the '80s and '90s remembers
the great old radio station WHFS and Weasel the DJ. Weasel had a daily
feature called "My Three Songs"; in this game, he would present three
songs that had a common thread, theme, or leitmotif, and the object
was for the listeners to guess what it was.

Here are three items by Etsy artists. What do they have in common?
