This is a sincere question directed particularly at longer-tenured Kpop fans. I first got into Kpop in 2012, but it took a while for me to become really familiar with the genre. So I sort of missed the boat on Teen Top's heyday; by the time I was a serious fan, they seemed to be past the peak of their success. So here's my question: how popular was Teen Top during their glory days? Were they really an A-list group like I've heard some fans suggest? And if so, is there a reason why they don't seem as venerated in retrospect compared to other groups of their era? Thanks for the info!
