McGraw's other nominations were for best male vocalist, album (A Place in the Sun), single (Please Remember Me) and music video (Just to Hear You Say That You Love Me). He'll get two trophies if he wins the best album or single awards, as a producer.
Singers Brenda Lee, Sherrie Austin and Brad Paisley announced the nominees in the courtyard of the Grand Ole Opry House. The winners will be announced Sept. 22 during a ceremony broadcast live on CBS-TV.
Vince Gill, who has won the most awards (17) in CMA history, will be host of the show for the eighth straight year. He got five nominations: best male vocalist, album (The Key), song (If You Ever Have Forever in Mind) and two nods for best vocal event for duets with Patty Loveless and Sara Evans.

The most notable breakthrough this year was that of the Dixie Chicks -- Natalie Maines and sisters Martie Siedel and Emily Erwin. Along with the best entertainer nomination, the group's Wide Open Spaces is up for best single and video. They'll also compete with Alabama, Diamond Rio, Lonestar and The Wilkinsons for best vocal group.
