Thank you, Matt!
Anyways... I do hear the voice, and I don't want to get my hopes up, but I'm almost positive that it's Adele. It sounds just like her. Before that, it sounded like that same voice said, "Hello", and that's what convinced me it was her, because it's exactly how she says "hello". God... I'm literally about to cry at the very thought that she'll even be there. I don't know how the Grammys could keep this so top-secret, but God... If she's performing, I think I'll lose it.
