I - V - vi - IV

Also known as the pop progression.

Four chords that turn up in an almost suspicious number of hit songs from the last several decades, across genres from arena rock to power ballads. Starting on the tonic and landing on the subdominant leaves the progression wanting to loop straight back to the start, which is exactly why it works so well under a repeating chorus.
