When you think of boy bands, people automatically go back of the classics – ‘NSYNC, Backstreet Boys, 98 Degrees. And then, of course, there are the newbies – One Direction, The Wanted, Big Time Rush, you get the idea. But what about those few that were in our hearts for a split second, who we thought we would love forever, only to find out that they just didn’t have what it took to be a part of the competitive world of boy bands?

In honor of National One Hit Wonder Day (yes, it’s a real thing), let’s take a look at some of our favorite one-hit wonder boy bands. The teenybopper in us is getting giddy all over again.
