All this thread is missing is "Dancing Queen" by Abba and "Beat It" by the late MJ. I guess that someone did nominate "Sweet Caroline"...
Seriously, though, I'd give props to "Bohemian Rhapsody". That's a classic and a good suggestion. How about "Light My Fire" by the Doors? "Friends in Low Places" by Garth Brooks.
Good choice! I bought his cd "Facing Future" when I was in Hawai'i. I still put it in and play it before I go to work sometimes to calm myself and keep myself from firing all of my employees.
