I’ve always been fascinated by true one-hit wonders: the artists who had a song go to No. 1 on the Billboard pop charts, then never again reached the Top 40. I figured this was the kind of thing that happens pretty rarely—it seems like any schlub who has a No. 1 hit would then carry enough clout to put at least one more song on the charts.

But I didn’t really know how often it happened, because near as I can tell, this list hasn’t been compiled anywhere else. So I had to do it myself.

Let’s start from the inception of the Billboard Hot 100 on October 13, 1958, and carry through to 2009, five years ago. (This list includes only the primary credited artist, not any featured artists who failed to chart again.) It doesn’t seem fair to treat Meghan Trainor as a one-hit wonder just because she hasn’t followed up “All About That Bass” with another hit yet. The biggest recent omission would be Gotye, whose “Somebody That I Used to Know” went to No. 1 in 2012. You and I and even Gotye himself all know he’s not going to have another hit, but we’ll pretend otherwise for the time being.
