So it turns out there are a heck of a lot of one-hit wonders!
According to an analysis of every artist that's appeared on Billboard's Hot 100/Top 100 chart between 1955 and today, about half of the artists that appeared on the chart never reappeared. That means that almost half of pop successes are one-hit wonders! This is pretty sad for a huge group of people. But maybe when they die, they go to a heaven where it's always the week their song was on the chart and they feel awesome.
Here is a photo of the chart. Have a look then tell us your favorite one-hit wonder in the comments below.
