Details: Two CD pressing. Naughty Boys was YMO's sixth album, released in May 1983 and undoubtedly one of the best synthesizer pop albums ever. Naughty Boys has a different sound and leans more to the Japanese pop music scene than previous albums. Nevertheless, this is a solid dance album! 'Kimi Ni Mune Kyun' and 'Lotus Love' stand out as most famous and loved by fans. The second CD, Instrumentals, was released in July 1983 and is the instrumental version of Naughty Boys featuring additional synthesizers, a completely different running order and include different versions and mixes.
