The teen sensation Bieber also received the Favorite Pop/Rock Male Artist, T-Mobile Breakthrough Artist of the Yer and Favorite Pop/Rock Album for My World 2.0. His mentor Usher won the Favorite Male Artist T&B.

Taylor Swift further solidified her country music credentials by winning the Favorite Country Music Female Artist award. Her new album Speak Now has been breaking records, reaching one million copies sold within a week of release.

Brad Paisley bagged Favorite Country Music Male Artist. Paisley has been previously declared as Entertainer of the Year by Country Music Association so it could be said he had this one from the AMAs on the bag from the beginning. No contest there
