Wake Up to a Song

Do you wake up in the morning singing a song? Sounds idyllic, but it's kind of weird really. Every morning when I wake up, there's a song in my head, and it usually stays all day. It's never anything like "The Hills Are Alive with the Sound of Music." It's things like "Greasy, grimy, gopher guts..." or "The Wabash Cannonball." Yesterday it was "Who's Afraid of the Big Bad Wolf" and today it was "I'll take you home again Kathleen..." Now where on earth did THAT come from? I guess I should be thankful that I wake up "with a song in my heart," but it gets annoying when the song sticks with me every waking minute.
