Idols Finale - Country Vs R&B

Next week, Kree Harrison, the country singer who's been kicking around Nashville since she was 10 years old, will face Candice Glover, who tried out for American Idol three times and finally will get where she has always dreamed of going.

That means Angie Miller, the piano-playing 19-year-old from Massachusetts who many had considered the favorite all season long, went home Thursday.

But Harrison's powerful combination of a moving homecoming story and an emotion-wracked performance of Rascal Flatts' Here Comes Goodbyeproved to be too much to overcome, as did Glover's commanding performance of Somewhere.

Season 10 runner-up Lauren Alaina returned to Thursday's show to debut her new single, Barefoot and Buckwild. Alicia Keys performed Tears Always Win, and Mariah Carey debuted the music video for her new single, #Beautiful.

Also, Ryan Seacrest announced that Season 8 runner-up Adam Lambert will perform "a surprise duet" on next Thursday's finale.

And, as soon as that show's done, online auditions for Season 13 will begin. (That season, by the way, will not include original judge Randy Jackson, who announced Thursday that he's leaving the show.) And the in-person auditions start in July in San Francisco, with Boston, Atlanta and Detroit among the other cities on the summer schedule.
