While a handful of American Idol finalists stood out last night - from Kris Allen to Matt Giraud to Allison Iraheta - viewers only had one performance to talk about after the show ended.

Adam Lambert slicked back his hair and sang an acoustic version of "Tracks of My Tears." It was incredible.

Here's a rundown of which artist sang which Motown hit:

• Matt Giraud - Let's Get It On
• Kris Allen - How Sweet It Is
• Scott MacIntyre - You Can't Hurry Love
• Megan Joy - For Once in My Life
• Anoop Desai - Oooo Baby Baby
• Michael Sarver - Ain't Too Proud to Beg
• Lil Rounds - Heatwave
• Adam Lambert - Tracks of my Tears
• Danny Gokey - Get Ready
• Allison Iraheta - Papa Was A Rolling Stone

Do you think anyone can beat Lambert? We don't.
