I think I hear "I don't think that's true" more than "I think that's not true." Is there any difference? If there's no difference, which one is better or natural?

The song definitely says "I think that's not true" but you are correct that you will hear "I don't think that's true" more often. That is because "I don't think that's true" is more natural and also more grammatically correct. I think they chose "I think that's not true" because it sounds a little silly and this is a silly/joke song. The meaning between the two however, is exactly the same.
