Billboard #1 hits gave the contestants the option of singing a new or old song. Often, the finalists went for tunes that were tried and true. The best was from Crystal Bowersox, whose confident and easygoing take on the classic ''Me And Bobby McGee,'' made famous by Janis Joplin, felt as comfortable as a well-worn slipper. The worst was season 9's Paige Miles, who inexplicably picked the dreaded ''Against All Odds'' and was so pitchy throughout, Simon Cowell said, ''It was like there was five of you singing that song.'' Paige was eliminated the next night.
