Fictional K-pop bands zoom to top of US music charts

I'll admit that there have been times I've been listening to those hour-long music videos (but not "music videos" you know) on YouTube, and only thought to check they were AI later. I was very disappointed to find out they were. Really wish there was attribution to the training material. The good news is that it doesn't look like this is AI, so we may just be returning to a time where physical appearance of the artist doesn't matter vs their talent.

This is just an animated movie sound track which had a normal production team and voice actors.

There have been fictional bands before like the Archies or Sabrina and the Pussycats. What's old is new again. Why pay some human who will often get a big ego and a drug abuse problem too?
