On her early albums, several famous 1970s Japanese singer-songwriters who had not yet succeeded at that time sang as the backing vocalists; Tatsuro Yamashita, Taeko Onuki, Akiko Yano and Minako Yoshida. Yamashita usually arranged the chorus parts of her songs in the '70s. But in later years, he criticized her late 1980s music career in his own song called "Queen of Hype Blues". In her career spanning more than 30 years, Matsutoya has sung duets with many singers; including Takao Kisugi, Toshinobu Kubota, Masumi Okada, and Takao Tajima.
