There are different ways to build a top-ten list. The way I employed for this list is twofold: pick the top song, then poke around to see if I could build a sensible list leading to this song. When I first thought of this list, I knew right away which song I’ll put at the top. My decision was pretty firm. It grew firmer when I made an important discovery that, as far as I know, has never been made by anyone before.
