Naughty Boys (1983) was Yellow Magic Orchestra’s sixth and final album to top the Japanese Oricon Pop charts. ‘Kimi Ni Mune Kyun’ also became the highest charting single by a technopop artist on the Oricon charts, debuting at #2. 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. 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.
