'IT' may be a charismatic presence which exudes confidence and which gets LOTS of attention... but that doesn't mean 'everyone' will enjoy or approve of that particular charisma.
I have NO interest in the Lady Gaga type....or Amy Winehouse... no matter how they affect others. I did finally see videos of Elvis in stage performances, and I now understand why he entranced many... but I just don't care for that type of music...(well, except for a couple odd items)

I have known local friends or strict amateurs who had more 'it' than many pros. I have seen some pros who had much talent, but no 'it'...including a couple who were almost offensive in their attempt to make the performance about themselves instead of the music. (In my opinion, Elvis was usually about *Elvis*, rather than presenting a song.) Some wonderful performers make you feel the song(s) so well, that you DO identify them with with 'it', just because.... (our late friend, Barry Finn was a prime example... he TOOK you places without ever pushing 'Barry'.)
