This to me is the most confusing of Mariah's performances. I at first thought it was pre-recorded and some parts may be but the section starting at 2:14 is certainly live. i know we have some people here with phDs in Mariah Mannerism for Live Singing and i think that section fits the bill. why mariah would sing only that section live i don't know. so for me this is a really baffling performance. i think it came off well but it was just strange.
