I used to learn songs from piano tutorials like these, too, and had to do the manual work of annotating keys and chords. It’s nice to see a very real pain point being eliminated — maybe I’ll even find some new songs to learn :)
While neat from a technical perspective, this seems like a solution in search of a problem.
EDIT: On the other hand, a cursory search did not find any midi/piano sheet music for "Hi Nanna: Samayama" - so maybe only having this "falling note video" is more common for certain music.
