Momoland isn't a one-hit wonder. In the summer of 2018, "Baam" nearly cracked the Top 10 on Melon and consistently ranked 2nd or 3rd on music shows, competing with heavyweights like BTS, Blackpink, and Twice. It's a solid hit.
Brave Girls also aren't one-hit wonders; they've had three top 3 hits. While "Rollin'" gained attention during their resurgence, "We Ride" was a top 5 hit, and "CMBR" was a massive summer smash for girl groups that year. Even their subsequent releases made it to the Top 50 despite lacking promotion.
Pentagon's "Fifty Fifty" fits the one-hit wonder bill, and while "H1-KEY" might be debatable, "Thinking Bout You" is gaining traction on Melon, suggesting their next comeback could fare well.
