Did Aaron Kelly know how many times "Ain't No Sunshine" has been performed on "Idol" over the years? Beyond Kris Allen's version last year, no. "I didn't go back through [past versions] because when I pick a song, I don't want to copy anybody, I want to make it my own," Aaron said. "So I didn't listen to anything but the original, and Kris Allen's was the only version I was aware of that's been done on the show." Lee Dewyze, on the other hand, always does his research. "I look it up," Lee confessed. "If someone killed that song, I don't wanna get up there!" Michael Lynche had a more philosophical view on the subject: "You're not the first person singing that song, but you've got to approach it as if it's your song. Like, what does it mean to you, regardless of who sang it."
