"Ride On Time" is a classic Yamashita song: summery and soaring with guitar and sax. Unlike his wife's initial retro-pop and later straight-ahead pop, Yamashita's tunes have a bit more rock, R&B and funk mixed in. It's ironic, then, that his most famous tune happens to be a Xmas song.
In any case, "Ride On Time" got as high as No. 3 on the Oricon charts, and its album of the same name, was at the No. 1 position for about a week in October 1980. Over 20 years later, the song became the theme of a popular drama called "Good Luck" starring Takuya Kimura(木村拓哉）, which gave it a return to the charts, getting as high as 13th place.
