Sweetest Music

The track opens the album and was released as her sixth single on December 5, 1980, the same day, with "Morning Glory" by Tatsuro Yamashita on the B-side. Words are by David Lasley and music by Peter Allen. The players were Jay Graydon and Steve Lukather on guitars, David Foster on keys, Jeff Porcaro on drums, David Hungate on bass, and Bill Champlin, Tom Kelly and Carmen Twillie on backing vocals. Takeuchi said that following up "Futari no Vacance" was a major challenge. The fan site fozfan calls it a delicious pop and disco up-tempo. It also appears on Viva Mariya!! (June 5, 1982) and Turntable (September 4, 2019), and a live version from 1981 is on the 2019 Miss M remaster. The single jacket photograph, taken in the US by Alan Levenson, was later used as the thumbnail of the "Plastic Love" fan upload.

Superfly (Shiho Ochi), who first heard it at Takeuchi's Budokan concert, recorded it for the limited-edition bonus cover EP of White (May 27, 2015), with Takeuchi singing as a duet guest. Takeuchi told Billboard Japan she was happy to have the 30-year-old song brought back to life. We found no chart entry, no statement on the lyric, no video and no setlist count.
