Genuine question: Does knowing English well help a KPOP artists' popularity internationally? (Or releasing full English songs, mainly English songs or English versions of released songs)
In my personal opinion, I think that it does. Blackpink is super popular internationally, as well as domestically and 3/4 members are fluent in English. 4/8 of the songs on The Album are in English or almost all English and I think this has helped them grow even more internationally. BTS released Dynamite (an all English song) and it broke many records everywhere and became mainstream in the West (I've heard it play multiple times on the radio like IHeartRadio and more and I live in the U.S.A). I'm not sure who's fluent in English in that group, I've heard Namjoon speak English a few times and he's really good at it. But they already had I-Army but I think the numbers definitely grew since then.
No Twice member is fluent in English but I think that their English versions are really popular also (I Can't Stop Me and More & More). They released two English songs (I Want You Back which was a cover but Twice style and it had a music video and What You Waiting For which was an English release on a Japanese album but I'm not sure how well it did but I listened to it and it was sort of hard to understand) but they are more popular domestically (mostly Korea and Japan) and they have a lot of I-Once already. For Itzy, they released English versions for all their title tracks very recently and I'm expecting those to do well in the West too. Plus Lia is fluent in English, though I'm not sure about the other members :)
So what do you guys think? Does releasing a (mostly, version, or all) English song or having a knowledge in English help a KPOP artist internationally?
