This is kind of a stupid way of measuring the most used songs. You're not counting songs that aren't put up for votes, which are prolly wildcard shows and specials, so you're ignoring 2 performances of "Saving All My Love for You" (S1 and S8 WC) and the 2nd Trenyce version of "I Have Nothing" (I think it was F5 when they did some stupid no-vote-off special). Basically, Whitney reigns supreme on this show.
