I consider myself more of a sound guy, but if the lyrics are great, I could forgive poor sound mixing and bad rhythm. That said, I'm a versatile listener, but I'm more geared towards a language I'm familiar enough to dissect and find meaning within.
Either I'm a buffoon or I don't listen to much KPop, but I find their lyrics to be pretty damn repetitive and shallow, even if I try to appreciate the language itself. It's either liking a girl or being cucked by love. I don't listen to much JPop either, so I can't make comparisons. Doesn't mean I can't enjoy nor recommend KPop music. Boy With Love had a killer hook, gotta admit.
