I can't choose one, but I could mention some of my favorites:
"Bohemian Rhapsody" -Queen
"Love Her Madly" or "Love Me Two Times" -The Doors ('Twas a difficult choice between many of their songs.)
"Rock You Like a Hurricane" -The Scorpions
"Hot for Teacher" -Van Halen
"Sharp Dressed Man" or "I'm Bad, I'm Nationwide" -ZZ Top
"El Manana" -Gorillaz
