Just watched this one ππΌ i know there was 15 min remix with alot more artists, hopefully someone has recommended that to you by now ππΌ also, there are collabs out there between companies, but they tend not to be promoted as heavily so they donβt get as many views (and thus arenβt recommended as much to newer fans). SM has actually had this program for a couple years, SM Station, where they have been releasing songs (with mvs) that arenβt tied to any group so there have been many collabs outside the company through that (ie Wow Thing - Seulgi, Chungha, SinB, & Soyeon). John Legend was even in an SM Station song with Wendy from Red Velvet.
A lot of times where you actually see the most collabs and interactions between groups from different companies tho is at the award shows, as well as other televised festival concerts. They almost always have special stages with collabs at those.
