Seeing as how today is Friday the 13th, I'm going with that theme today.
Stevie Wonder - Superstitious. I love this song. No matter how often I hear it, it always makes me happy, and I have to sing along. Maybe even dance a little, too.
Warren Zevon -Werewolves of London. Come on, you know you all like it, too.
AC/DC - Highway to Hell. I loves me some AC/DC.
Finally we have Simple Plan - I'm Just A Kid. Doesn't seem like a Friday the 13th song until you watch the movie. Pretty funny. If you only watch one of these, make it this one. Trust me.
