one of the biggest things people go to his concerts for, and prepare for their biggest reactions to, is when he sings 'She's Out Of My Life'. that's when girls are eager to rush the stage and hold him tightly throughout that song. you don't think people are listening to his voice then? you don't think that the girl holding him tight is listening to his voice, then? the original recording of that song is one of the greatest, if not THE greatest vocal performance in HISTORY.(i think it's THE greatest, cus i've heard top performances, but then i hear this one, and i hear THE top performance, plus a special otherworldly feeling from his voice alone.)
also..in 2001 he danced with NSync, and did not sing on mtv, to the NSync song, 'Pop'. he got an equally crazed reaction.
