One thing I've really gotten to like about anime music is that rock/punk seems to still be pretty popular in Japan, whereas it's been virtually entirely replaced by rap/autotuned club music here in the US. I can't understand a lick of the lyrics, but a ton of anime has really catchy and upbeat punk, and as a 90s teen, it brings back fond memories. I'm a (marginal to average) drummer and a lot of the songs aren't too hard to play and a ton of fun.
I'll start by saying Tu Love Ru's season one opener "Forever we can make it" by THYME (also the animation that goes with it in the show is👍)
Bravin' Bad Brew is an amazingly good OP for a literal forgotten series that no one but me watched because of how garbage it was.
The original Ranma OP is one I haven't gotten out of my head since the fucking 90s.
Also Rock the Dragon from DBZ is still the GOAT and that will never change.
