Admittedly, I wasn't a huge anime guy as a kid. I watched some of the normie stuff (some good, some bad) that some friends who were into it watched and recommended, but it didn't have too much of a lasting impact; I don't really remember any of the songs, aside from one, which I'll get to in a second.

I only more recently (last five years or so) got back into anime, because I wanted to try it out again, and was fed up with modern Western shit. Ended up loving it, and it's most of what I watch, entertainment-wise, now. Decades ago, the main stuff I watched was normie stuff; Kenshin, Yu Yu Hakusho, FMA, Death Note, Bleach, Naruto, etc.

As for songs that stuck with me, it's actually from some anime I don't remember the name of, and haven't been able to find. Maybe someone else will recognize it. It's probably cringe; I was a kid or young teenager when I watched it, and I think it was pretty heavy in the CGI, too. Anyway, it was some dragon-centric isekai-ish (I think they could go back and forth between worlds) anime, where different groups are having power struggles over the dragons in the other world. Yup, the anime itself is almost entirely forgotten, but I can remember the opening riff to the song, kind of rock-y as I recall, around two decades later. Weird what sticks with you.

EDIT: Fuck, that brings me back. Found it! Dragon Drive. Wow.
