I go gobbles when you are not here

The story:

It was on the radio and my mom asked us what the lyrics were, because she couldn't figure it out. She said it sounded like "I go gobbles." Neither me nor my brother had a better answer, so she listened to it about twenty times before she deciphered that it was really "my world crumbles." However, when we see Macy Gray on TV, she still always calls her "The I-Go-Gobbles Lady."
