Chicago
It's not so much what the song says, as what the song was. This song marked a turning point for Chicago: instead of horns and a Rock sound, it was Pop ballads and pianos. The Roman numerals in their album titles (like Chicago XIV) also disappeared. Chicago was one of the first Rock bands of the '70s to take on a softer, more keyboard-driven sound in the '80s. They were followed by Yes Owner of a Lonely Heart, Van Halen Jump, and Heart These Dreams onto the charts with this new sound.
