Adam Lambert, Allison Iraheta Steal the Show on American Idol Motown Week

American Idol's Top 10 Sing to Make the Final 9

The American Idol Top 10 were set to groove to Motown Wednesday night in Hollywood. And they should have been set. They were actually flown to Detroit, where Smokey Robinson and Berry Gordy, their mentors for Motown Week, showed them around where the Motown Sound originated. Then it was back to Hollywood to pick a song and get Smokey Robinson's help in making the song into a memorable performance.

First up: Matt Giraud. Smokey Robinson said about Matt's rendition of Marvin Gaye's "Let's Get It On," "Marvin would have loved that." And he just might have. Matt Giraud put his own soulful twist on the song. He began his performance on piano and then moved to center stage to sing the audience. Simon Cowell told him it was brilliant. Randy Jackson said that Matt had set the tone for the night. Kara DioGuardi said that all the girls now wanted to "get it on" with Matt and Paula Abdul said that Matt had a cool, sex vibe.

After Matt Giraud's performance, Kris Allen stepped sang "How Sweet It Is (To Be Loved By You)." (And how many of you thought that that was a James Taylor song?) With his acoustic guitar as prop, Kris Allen did a better-than-average job with a mediocre song. The male judges' remarks bordered on the cliché, more advice than criticism, but Kara DioGuardi liked Kris' rendition, stating that he had put his own mark on the song. Paula Abdul said he was "infectious." The women in the audience certainly were infected by him...
