Yeah anti Japanese would bother me as well if I caught it as I’m an anime and Jpop/Jrock fan as well. If Kpop artists wanted to encourage me as a fan they would develop positive rather than negative relationships with their Jpop counterparts.

As for Kpop all sounding alike how is that different than say American pop?

I prefer J-pop but K-pop isn’t all that bad.

I think Google justifies the whole process with ads. Sure it’s all piracy but you come for the music, pirated or not, and they sell ads to you and someone gets paid revenue. I think YT would have an easier time of it if they improved gemini and integrated it as a DJ like spotify has its own music DJ.
