"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 song was written by lead singer Steven Tyler and bassist Tom Hamilton, produced by Jack Douglas and recorded at the Record Plant.
The song and consequently the album that went into the Top 10 were so successful that the band decided to ride the heels of success and re-release one of their first singles, the power ballad "Dream On", which had originally charted at #59 in 1973. The re-released version went on to hit #6, the highest chart performance in the 1970s for the band. "Sweet Emotion" remains successful in the modern day, having sold over three million digital downloads.
