Thankfully, I've never really had that "problem". I think the amount of music I play through and listen to on a daily, weekly basis sort of prevents me from having any one particular tune stuck in my head at one point and time. I see it as a sort of self-defense/self-preservation mechanism... -If I had "Gimme, Gimme" and "Shiksa Goddess" constantly running through my head... OY! If I do find myself humming something, it's usually something random and non-specific.
God is GREAT, Jose. Some day, this will happen to you, too. He's just toying with you for now.
Pray, however, that it isn't "Teddy Bear's Picnic"!!!! Oy!
(Second worst possibility: "Yummy, Yummy, Yummy, I've got love in my tummy...").
