5. Cowboy Bebop – “Tank!” by The Seatbelts

I remember the exact day I heard this song for the first time: one of the artsy kids in my middle school had made a funny video for his class and the teacher wanted to share it with the school. This was the song he made his video to, and I just had to know where it came from. And that’s how I became a proud owner of a Cowboy Bebop collector’s edition set.

But really, The Seatbelts are beyond talented. This song is impossible to sit still through.

4. Demon Slayer Kimetsu no Yaiba – “Gurenge” by LiSA

I do not know Japanese. But I know every word in this song.

When I started watching Demon Slayer, I found Tanjiro beyond annoying and was having a hard time getting interested in the story, so I decided to latch on to the theme song and beloved Nezuko as a reason to keep watching. I’m glad I did as I am now obsessed, and this theme song still gives me life to a crazy degree. LiSA is an amazing vocalist.

I like the other arcs’ opening songs as well, but none of them will ever compare to just how glorious this one is.
