Just a nitpick, not meant to detract from the geeky awesomness of the project.

I think the service to match the songs to play clips has gotten confused by some part of this, either the Japanese text or the Musicbrainz convention of putting the composer (in this case Neil Diamond) as the main "artist" in orchestral works which makes sense for an Ennio Morricone collection, but is somewhat surprising when the "composer" is a pop star.
Some details on the cover from Wikipedia:
In 1966, famous Italian singer Gianni Morandi recorded a cover version titled "Se perdo anche te " ("If I lose you too"). The author of the Italian lyrics was Franco Migliacci, who was Morandi's producer at that time, and eight years before had written the lyrics to Domenico Modugno's international hit "Nel blu, dipinto di blu (Volare)". This song was arranged by Ennio Morricone, who at that time conducted many tunes published by the Italian RCA Victor, and was the B-Side of "C'era un ragazzo che come me amava i Beatles e i Rolling Stones " ("There was a boy who, like me, loved the Beatles and the Rolling Stones"), a song against the Vietnam war.
