I'm a weeb so 90% of the Japanese songs on my playlist are from anime. My most listened to song on youtube music for three years running is Kyoumen no Nami

Aporia and Deep Indigo share a distant second place

My favorite has to be YURiCa's (also known as Hana-tan) cover of Yuuyu-P's Tengaku . It gives me goosebumps everytime I listen to it and an overall feeling of "pushing foward no matter what" that I don't think any other song has managed to replicate for me. I'm so glad I discovered it.

Probably Ado's 新時代, but honestly, pretty much any Ado song competes for the number one spot.

Otherwise: ビビデバ

Mine has to be the second opening of Eureka Seven

I have so much respect for Studio Bones for creating what I believe to be one of the most culturally important animes with a deep environmental message that still resounds to many nations and peoples to this day.🫡

That and gods damn the music, the vibes, the action sequences, and emotional weight is like peak in E7🤌✨

For me, Minami's Hollowness has been sitting in the number 1 spot for the past 2-3 years (although I've discovered the song in 2019). I particularly love the lyrics for this one, so make sure you turn the English subs on, unless you know Japanese. Hollowness wasn't always my favorite Minami song, but my favorite song has consistently been from Minami ever since I discovered her in 2019. It was just a matter of which one.

Then, in no particular order, my next 4 to round out the Top 5 are:

• Harusaruhi's Oogoto - My first introduction to her, still my favorite song by Harusaruhi. I did hear a couple V.W.P songs, of which she's a part of, before Oogoto, but this was my first song from her alone without the rest of the group.
• Ave Mujica's Symbol IV - Beautiful song that shot them up in my artist rankings a lot. Not that I don't love other songs by Ave Mujica though!
• MyGO's Shiori - Sometimes it takes me a while to warm up to a song. It's not always after my first listen. That's part of why I never skip an anime opening or ending, even when I'm not particularly into it: cause I know I might change my opinion drastically. Well, this isn't one of them. Love at first listen for MyGO's Shiori.
• Minami's Crying for Rain - Once upon a time my favorite Minami song, which is now Hollowness. Was also the first I've heard from her. And honestly, the only reason it's not number 1 still is cause I've listened to it way too much. Given some time, it might go back up.

シカ色デイズ by シカ部

Duh. Dir en Grey "Child Prey". Like is this even questionable?

Either Night of Assassins or The Night Collectors by Les Rallizes Dénudés. Love the distortion they brought
