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👍)
As someone who listened to Myth & Roid especially when that lead singer went on to make more herself then being asked to pick one
I have two seperate playlists, one just of Anime op & ed and one I can use to workout to. It depends on mood really as one day I can really fancy Long shot by Mayu Maeshima then another I might fancy something sombre like One Last Kiss by Hikaru Utada
