The 1991 Mariah Carey album that includes the song “Emotions” is Emotions.
Released by Columbia Records on September 17, 1991, Emotions was Carey’s second studio album, following her self-titled 1990 debut. Its title track became one of the defining recordings of her early career and served as the album’s lead single.
The song “Emotions” was written and produced by Carey with David Cole and Robert Clivillés of C+C Music Factory. Its gospel, R&B, disco, and dance-pop influences gave the album a more energetic sound than some of the ballad-heavy material associated with her debut. Carey’s extensive whistle-register vocals are especially prominent on the title track.
A common mix-up is confusing the album with the single: both are called Emotions, but this question asks for the album. The album also includes “Can’t Let Go,” “Make It Happen,” and “You’re So Cold.”
