What the hay happened to Mariah Carey‘s voice? Tell me why lately Mariah sounds like Mister Ed the talking horse?

She half lip synchs on Good Morning America this morning much to her fans chagrin. And when she wasn’t lip synching she was forgetting her lyrics. At one point she told her back up singers, “Stop singing my parts now, bay-bay.” What???
