Fresh off his band Daughtry taking home 2007 American Music Awards for Favorite Adult Contemporary Artist and Favorite Breakthrough Artist -- while the group's self-titled debut album was also recognized for Favorite Pop or Rock Album -- Daughtry received three Grammy Award nominations.
The group's self-titled debut was nominated for Best Rock Album, while one of its singles -- "It's Over You" -- received a nod in the Best Rock Song category. "It's Over You" was penned by Daughtry and songwriters Gregg Wattenberg and Mark Wilkerson, as well as Daughtry's fellow fifth-season Idol finalistBrett "Ace" Young.
"Home" -- a ballad that served as background music for Idol sixth-season eliminations -- received a nod in the Best Pop Performance By A Duo Or Group With Vocals category. In addition, the album's producer Howard Benson was nominated for Producer of the Year.
Underwood -- who took home two 2007 Grammy Awards for Best New Artist and Best Female Country Vocal Performance for "Jesus Take the Wheel" -- received three nominations this year.
In addition, Underwood's "Oh Love" duet with fellow country crooner Brad Paisley -- a track that appeared on his sixth album "5th Gear" -- also received a Grammy nomination for Best Country Collaboration with Vocals.
Underwood and Paisley will be pitted against Clarkson and her best bud Reba McEntire in the Best Country Collaboration with Vocals category, in which they were nominated for their duet "Because of You."
Like Underwood, Clarkson also already has two Grammy Awards to her credit. The original Idol champ's sophomore album "Breakaway" won a 2006 Grammy for Best Pop Vocal Album, while its single "Since U Been Gone" received the Best Female Pop Vocal Performance Award.
Barrino received her Grammy nod in the Best Contemporary R&B Album category for her second album "Fantasia." The Idol third-season champ's debut album "Free Yourself" received two 2006 Grammy nods in the Best Female R&B Vocal Performance and Best R&B Album categories, however she failed to receive either award.
Hudson received a Grammy nomination in the Best Song Written For Motion Picture, Television or Other Visual Media category for the Dreamgirls' song "Love You I Do," which was written by Siedah Garrett and Henry Krieger. The Dreamgirls actress -- who received an Oscar for her role -- performed "Love You I Do" in the film.
Rounding out the nominations was Hundley -- Idol 5's ninth-place finisher -- who received a Grammy nod for her debut album "True Beauty" in the Best Pop/Contemporary Gospel Album category.
The 50th Annual Grammy Awards are scheduled to air live from Los Angeles' Staples Center on Sunday, February 10 at 8PM ET/PT on CBS.
