The only song not included in any album is Amaku Kiken na Kaori which is only released as a single and a re-recording of Funky Flushin'.

According to Yamashita, "Greatest Hits" is just a mundane joke that I thought of as a western music lover.

[1] The original album release (RAL-8803) included Yamashita's biography, discography, and various photographs in the form of a booklet.

In 1990, BMG Victor told Yamashita of its plans to release the album, and it asked Smile[nb 1] to provide technical help for the project.

It was not until February 1991 that when Yamashita received a fan letter complaining that some songs of the album's 12 tracks were different from the previous versions.
