When I was studying in Kyoto two years ago, I didn't have to take the subway a lot since I lived a few minutes far from my university...
But one day, on my way back home after a music gig, as soon as I went in the subway, I heard this and freaked out... (it starts at 00:12)
...Yes, this is EXACTLY the same melody as the Song of Healing from Zelda Majora's Mask, except that it is the jingle everybody hear every two minutes in the Kyoto subway !!
The fact that Nintendo is located in Kyoto and that both songs sound exactly the same is NOT a coincidence... it cannot be... right ?
Anyway, I let you imagine how surprised I was...
