Please tell a story about the music ya'll chose for this, it's incredible.

You mean the song in the trailer? It's the japanese OST for Kenshiro: https://en.wikipedia.org/wiki/Kenshiro

The story is quite simple, I just loved the anime when I was a kid :)

The italian version is also incredible: https://www.youtube.com/watch?v=YPIcdhjPG5I
