Updated: Sept. 10, 2009, 6 p.m. ET. -- This story was updated to reflect Brad Paisley and Keith Urban's additional CMA Awards nomination for "Start a Band." The CMA omitted the performance from the musical event of the year category when the nominees were officially announced on Sept. 9.

With seven nominations, Brad Paisley emerged as the frontrunner when the nominees for the 43rd annual CMA Awards were announced Wednesday (Sept. 9) in New York and Nashville. Keith Urban followed close behind with five nominations, and Jamey Johnson, George Strait, Taylor Swift and Zac Brown each received four.

Darius Rucker and Lee Ann Womack announced the final nominees in five of the 12 categories during a telecast Good Morning America at the ABC News studios in New York's Times Square. Randy Houser announced the candidates in the other categories at CMT's studios in Nashville on Insider Special Edition: 2009 CMA Awards Nominations, hosted by CMT personalities Cody Alan and Alecia Davis.

Rucker, once primarily known as the lead vocalist for Hootie & the Blowfish, picked up his first CMA nominations as a solo country artist. He's nominated in the new artist and male vocalist categories. Womack and Strait share a nomination for musical event of the year for "Everything but Quits," a duet featured on her Call Me Crazy album.

In addition to nominations for entertainer of the year and male vocalist, Paisley received an album of the year nomination for American Saturday Night and single and song of the year nominations for "Then," the single he co-wrote with Chris DuBois and Ashley Gorley. Paisley's collaboration with Keith Urban on "Start a Band" netted a music video of the year nomination for them and director Jim Shea. "Start a Band" is also up for musical event of the year.

Urban's other nominations include entertainer of the year, male vocalist and album of the year (for Defying Gravity).

Strait also received nominations for entertainer of the year and male vocalist, along with music video of the year for "Troubadour," directed by Trey Fanjoy. Strait and Womack won the CMA's musical event honor in 2005 for their collaboration on "Good News, Bad News."

Swift's four nominations include her first for the coveted entertainer of the year prize. She is also nominated for female vocalist and music video of the year (the latter for "Love Story," directed by Fanjoy.) Swift's Fearless is nominated for album of the year.

Johnson, a new artist nominee, is also up for single and song of the year for "In Color" and album of the year for That Lonesome Song. He won a CMA song of the year award in 2007 for his work with co-writers Bill Anderson and Buddy Cannon on Strait's hit, "Give It Away."

Brown received his first CMA nominations Wednesday. The Zac Brown Band is included in the new artist and vocal group categories. The band's hit single, "Chicken Fried," is nominated for single of the year, and Brown garnered an extra nomination for co-writing the song with Wyatt Durrette.

This year's CMA Awards will be broadcast live Nov. 11 from Nashville's Sommet Center. Paisley and Carrie Underwood will return for a second year to host the ABC telecast.
