Yamanot.es: A music box of train station melodies from the JR Yamanote Line

Unfortunately JR East has phasing out the custom melodies and have been standardizing the Yamanote line to always play the same tune. They are saying labor shortages are the reason since they need to press a physical button in the station in order to play the melody.

Huh.

My impression is that all of the Yamanote line stations are above ground -- I'd have expected it to be possible to have "one button plays the right sound at each station" if you used a standard phone's GPS to figure out which station you were at.
