Leading the former Idol finalists in 2007 AMA nominations is Daughtry's band Daughtry, whose self-titled debut album dropped last October; spent two weeks at No. 1 on The Billboard 200 album sales chart; and is certified triple-platinum by the Recording Industry Association of America (RIAA) for selling more than 3 million copies.
Daughtry received 2007 AMA nominations for Favorite Adult Contemporary Artist, where it will compete against Norah Jones and John Mayer, as well as Favorite Breakthrough Artist, where the band will face Plain White T's and Robin Thicke.
Daughtry's self-titled debut album was also nominated for Favorite Pop or Rock Album and is pitted against Linkin Park's "Minutes to Midnight" and Justin Timberlake's "FutureSex/Love Sounds."
Underwood is no stranger to being honored at the American Music Awards, winning Favorite New Breakthrough Artist in 2006 and also being nominated for Favorite Country Female Artist. This year, Underwood was once again nominated in the Favorite Country Female Artist category -- where she'll face Martina McBride and Taylor Swift.
In addition, her debut album "Some Hearts" was also nominated for Favorite Country Album and is pitted against Tim McGraw's "Let It Go" and Rascal Flatts' "Me and My Gang."
Fantasia -- who is currently playing the role of Miss Celie in Oprah Winfrey's Tony Award-winning Broadway show The Color Purple -- received a 2007 AMA nomination for Favorite Female Soul/R&B Artist, where she'll compete against two other one-name singers, Beyonce and Rihanna.
Fantasia previously received 2005 AMA nominations for Favorite Soul/R&B Female Artist as well as for Favorite Soul/R&B Album for "Free Yourself."
In addition, the Dreamgirls soundtrack landed a 2007 AMA nomination for Favorite Soundtrack. Idol 3 seventh-place finisher Jennifer Hudson -- who won an Academy Award for her for her portrayal of Effie White in Dreamgirls -- contributed to the film's soundtrack.
