Don't know much about TXT except maybe a couple of songs, but nothing wrong with collabs if it benefits both artists, artistically, exposure to different fans, expanding musical genres. It's great, of course kpop fans only see the bottom line about everything in terms of sales and charting.
They'll have another Western collab? Is that the second or third in 2022? Either way it will give a boost to their MLs for 1-3 months but I don't see it having lasting impact on their career. Marshmello fell off years ago, just because he touches something it's not going to be hyped.
