“Imagine” is his biggest hit because girls like sappy, simple, loving, caring ballads. This song is bullsh&%, but it makes girls cry. That works in the record biz.
“Color My World” by Chicago is one of thier biggest hits. Simple chords and lyrics that make girls cry while they slow dance.
Color My World was the theme of my Senior prom. An event which my steady girlfriend of two years decided to use to break up with me. Such a fun evening.
