Naughty Boys (1983) was Yellow Magic Orchestra's seventh and final album to top the Japanese Oricon Pop charts. After that, no Technopop artist was able to reach No.1 until Perfume's 2008 album Game. "Kimi Ni Mune Kyun" also became the highest charting single by a Technopop artist on the Oricon charts, debuting at No. 2; a record the song retained until Perfume's "Love The World" debuted at No. 1 in 2008. A remix album, Naughty Boys Instrumental was released in July 1983. It contained nearly the entire Naughty Boys album as instrumental tracks in an entirely different running order, as well as the b-side to "Kimi Ni Mune Kyun", "Chaos Panic"; and the full instrumental version of "You've Got to Help Yourself", of which the vocal track was included on Service [MOVLP1473]. Naughty Boys Instrumental featured additional synthesizers imitating the vocal lines, as well as new embellishments and mixes. Several tracks featured sonically updated percussion tracks, while "Ongaku" featured an acoustic piano soloing over the piece. Naughty Boys & Instrumental is available on black vinyl and includes a 4-page booklet.
