I've done things like that. It freaks out the people around me more than it does me at this point. I'll be humming or talking about a song, get in the car, turn on the radio, and that song will be on. And I'm not talking about the popular it song they play every 5 minutes. It can be any song. I've had it happen and then changed the station and it's playing again. My mother calls me a witch. :D
