I don't mind the singing during the high energy songs. I know that as a writer, it's awesome when people know the words to what you've written by heart. So I'm sure that for Kelly, the biggest thrill is when an audience of thousands are singing words she wrote and songs she's created. It's a pretty cool feeling...so i don't mind it.

But I'm with a lot of people...during acapella songs or very slow emotional songs, it's nice to get the performer's entire emotional take on it and not the audience's.
