I heard Aerosmith's "Angel" on the radio today--a favorite of mine when I was in high school, I admit with some blushing. In fact, I listened to Aerosmith, Poison, Bon Jovi, and similar bands so nearly-exclusively that for a while I thought all rock songs were required to follow this structure or they'd get disqualified somehow:
Verse Chorus Verse Chorus Guitar solo Bridge Chorus (repeat and fade out)
I had to undergo something of a mental shift when I later encountered pop songs that didn't have a bridge or a guitar solo, or any instrument solo at all; and that simply ended the song instead of fading out. Imagine such innovation!
