Sweet Emotion. Sweet Emotion is a song by the American rock band Aerosmith, released by Columbia Records in April 1975 on the album Toys in the Attic and was released as a single a month later on May 19. The song began a string of pop hits and large-scale mainstream success for the band that would continue for the remainder of the 1970s.
The music was based on the bass line Tom Hamilton came up with. Tyler wrote the lyrics (Perry was known as Mr. Sweet Emotion), and they put the song together in a jam session. Hamilton says it was the band's producer, Jack Douglas, who coaxed the bassline out of him.
