If you have ever been to Tokyo, you must have taken the Yamanote Line around town. Here are the melodies for the different stations. Sometimes, when I have an hour to spare, I take the Yamanote Line one way around, but I do hate the recent all-video trains. Let's keep the stress level down, shall we. Please, less ads, more train pleasure.
Still, the JR East Yamanote Line has to be the best service around.
