I remember listening to a couple songs from a japanese train company youtube channel a couple years ago and I really can't seem to find them any more. It had really pretty and fluid b&w pencil-like animation overlayed on top of irl footage overlooking the outside of a train window, and each song was named after a train line (maybe city?).
One song in particular had two versions (no animation vs animation), with a different vocalist singing each one.
I used to follow an artist who animated one of the vids on my old-old-old twitter account but I've lost track of them. If you recognize any of these traits or these videos, please lmk!
I will seriously pay you ten dollars if you find these sets of videos. I'll probably post a couple clips of me humming the melodies of a few notable ones just for documentation. I'm really desperate man :(
