I feel like publishing what songs followed me around in my head while I was in Japan, so I’ll list them here:
Kyoto and rural areas: Xyce – A summer afternoon
Crossing over Rainbow Bridge: Mirror’s Edge menu theme
Tokyo: Bôa – Duvet
Plane taking off back to Japan: SAVESTATES – When They Find You, Don’t Tell Them You’re Dead
After returning to Japan: Zabutom – My alien shoes
I think they are fairly dumb song choices, but I really could not get them off my head, so if you want to add to the atmosphere while reading the trip account of Japan, you can play the corresponding song.
Not sure why anyone wants to know this, though.
