No full English singles or six discount remix version gimmicks. Which existing group do you think will be the next to chart with a regular Korean title track and then continue to chart on US BB100 for the rest of their careers? I believe the only Korean acts to ever chart more than once are PSY, BTS, Blackpink, Lisa, and Suga.
Honestly, I don't think anyone can do it out of the groups that have already debuted. There was a time I thought TXT could, but BH is not giving them the right songs...Same with ITZY after Wannabe charted on Canadian Hot 100, but then the music went downhill.
