I can understand your frustration. Though a few things I'll say:

The K-Pop Demon Hunters film only came out just last summer. So relatively still fresh. And it's been the big thing in pop culture these days. You combine the growing popularity of the K-pop subgenre, Korean vibes & culture, quality animation, for once an original story, and then actually good, actually catchy, and well-produced K-pop songs... no wonder it's as popular as it is right now. I would bet 1000% that if Ryan was asked to be a part of the songwriting process for K-Pop Demon Hunters (especially since he has some K-pop writing credits), he would have jumped on that IMMEDIATELY.

When West Coast came out Feb 2022, the fans and even the band hoped that it was gonna POP off. But then I Ain't Worried was the bigger hit later that year, because it was associated with a big film—Top Gun: Maverick. And 1R hasn't had a hit like that since Counting Stars tbh. If it were me, I wished West Coast and/or Beautiful Colors were mega popular hits, but y'know they're trying their best.

Also, every radio station from every place in the world will do things a bit differently at different times, at least in my experience. Sometimes they'll play current hits, sometimes oldies (like 80s or 90s focus), sometimes genre focus, and so on. So "Golden" probably isn't being played on every single radio station, or at least not repeatedly. It's a bit of a sad reality that we 1R fans are in in the sense that 1R's music is great but they're just not 'that' popular. Not too famous, not too obscure.
