How could anyone dislike babymetal ?!?
I was amused for a few songs, but there is no way I am going to spend time listening to Babymetal.
Once the novelty of the concept wears off...you're not left with much.
Perhaps in the future*, I will make the time.
Given a choice, there are other manufactured/corporate-created bands that I would rather spend my time with.
It's all about "suspension of disbelief"...I can't take Babymetal seriously right now (as a reference point, I take the theme songs from old tv shows and commercial jingles more seriously than Babymetal). For me, it is a function of time. Once fads fade, and the promoters have long been paid, and nobody remembers Babymetal, then I don't mind evaluating them and appreciating them (if I choose) on their "own" merits.
This is the same pattern I've used for a lot of pop music. I need some distance from it. I'm in no rush to embrace it now, (*)but if I listen to it in a few years and I like it, well, damn, that's great.
