Next on the list were Billie Eilish, Chappell Roan and Shaboozey, who earned seven nominations each.Taylor Swift, who has picked up more AMAs than any other artist over her career, received six nominations this year.

Beyonce's "Cowboy Carter," which took the top award at this year's Grammys, was nominated for album of the year and favorite country album at the AMAs. She also is in the running for favorite female country artist.

Fans will vote on the winners, which will be announced at a May 26 ceremony hosted by Jennifer Lopez. The show will be broadcast live on CBS PARA.O.

Nominations were based on performances on the Billboard music charts, streaming and album sales, radio play and social media engagement.
