The local train to Tokyo sounds EXACTLY like the intro whine of Killer Queen every time it pulls into a station.
The Phillip Glass music from Koyannisqatsi is either sampled or used by the Tokyo subway system; manic electronic keyboards telling you to get a wriggle on.
They also play bird calls throughout the underground; suppose the users aren't chirpy enough by themselves.
Starbucks plays jazz-lite versions of Marvin Gaye.
In Yoyogi park there are various live bands complete with drum kits and sound-systems; they play next to the sign prohibiting unsocial noise-making. Drummers play in a big group in the middle. Guys and gals in hip-hop attire play badminton. Students play frisbee. A large group practice an elaborate sword-fighting sequence; looks like they're a theatre group training for a Kurosawa epic. Violinist, accordionist and guitarist play wandering across the grass. Close behind solitary singers/poets/story-tellers preach to no-one.

This week I got a late Valentines card with the message "I'm always thinking of you" signed in undecipherable Japanese left on my desk. Before I got the chance to embarrass myself by asking what it said, one of the lady-teachers came to explain it was from all of them.
Also this week, one of my male students leaned out the window as I left school and yelled "See you darling."
