Different vibes JP song that I don't think that many people actually know the singer mostly known for other songs (踊り子, 怪獣の花唄) but this one imo is the best one tho I am a bit more of a rap enjoyer so there's that bias lmao www.youtube.com/watch?v=Gbz2...

On the topic of rap I didn't watch this show but someone who did showed me this song and it's actually been on loop in my playlist ever since The rap style singing mixed in with the 古风歌曲 style composition is so good www.youtube.com/watch?v=_J_3...
