A window, meaning, a length of time in which a group can make a huge splash and be overtly successful.
I've noticed that with K Pop, unlike most other genres of music, groups tend to have a certain amount of years to make an impact before they sort of fade away. Typically, it's within the first 5 years of the debut. If you don't make some kind of footprint in 5 years, it gets harder and harder to stay relevant.
For me, BTS has room for one more huge album, something at least on the level of MOTS: 7.
Blackpink is just getting started as long as they move forward with their music and build their audience. Of course, this means they'll have to do it in spite of YG.
I think Twice's window is just about closed, too little too late too much in between.
