Thanks! And yes, that's how I discovered them as well.
I've often said that anime is to 2010s Japanese rock what MTV was to 1980s western music. It's how you discover music.
My favourite Japanese band hasn't made a song for anime yet, though. ONE OK ROCK. They did license their song Vandalize to Sonic Frontiers (video game) and their song Prove to Beyblade X (anime), but they haven't been commissioned, or accepted a commission to make a song for an anime. Not like RADWIMPS, who were commissioned to do the soundtrack for 君の名は。 (your name.) and had some of the ideas in their songs influence Shinkai's writing process. (That was awesome. My favourite film, and not just anime.)
