Warning: potentially NSFW - language (for those still in offices)
The song in question is sung with a very clear voice, with minimal instrumental backing. That may suggest the limiting factor is Google's ability to parse songs, rather than users' ability to hum them.

Aha, so that's where I had heard it before!
'The song is best known under the alternative title "Sukiyaki". In Japan it refers to a Japanese hot-pot dish with cooked beef, the word sukiyaki does not appear in the song's lyrics, nor does it have any connection to them'
"An instrumental version of the song was played by NASA over the radio for the Gemini VII astronauts as mood music, thereby becoming one of the first pieces of music sent to humans in space."
Whistle and look up so you can't see these tears..
It managed to be a #1 hit in the US even!
