The 25th anniversary of the band's formation was celebrated in January 2003 with the reissue of their original album, "The Professor of the World",坂本龍一(Engineer: Ted Jensen of NYC's Sterling Studios, who won a Grammy this year for Norah Jones), YMO's ultimate 2-CD best-of collection is born. This time, two previously unreleased recordings (a standard number "Koibito yo gawa ni koni ni shite" with veteran jazz singer Mari Nakamoto and a commercial version of "Behind the Mask" composed by the professor), which were said to be impossible to find anymore, and an almost impossible to find end track from the movie "PROPAGANDA". (The end theme "M-16" for the movie "PROPAGANDA", the stereo version of "Kaisenshin" used in the Fuji Cassette commercial, etc.), 5 songs not included on the original album, and a single song from the re-released YMO [Techno-don] album. This is a best album.
