Depends on what kind of "rock" you mean.

Queen "Bohemian Rhapsody"
AC/DC "Back in Black" or "You Shook Me All Night Long"
Bob Seger "Main Street"
Van Halen "Running With The Devil"
Scorpions "No One Like You"
Phil Collins "Susudio"
Led Zeppelin "Kashmir"
Pink Floyd "Comfortably Numb"

And others too numerous to mention. Hope to be back soon. Couldn't resist the question.
