The vocal part don't match with the rest of the song!

That's how it often goes in Japanese music. The vocals are geniunely expressed less ''strict'' and more in a live setting. Since you comment these kinds of songs rather often here, you surely would know.

The vocals on its own aren't sung in a wrong tune, aswell.

(is this a joke?)

No, but i do notice that you criticize most songs on here with Japanese vocals. I get it, you don't like them, but you do really have to single this out every time? The track itself is pretty good, why not focus on that instead?
