Keith Urban's new album, Ripcord, has vaulted back to the top of the country charts and now he's topping the list of nominees for the coveted Academy of Country Music awards. Ripcord is a boundary-pushing album that has spawned several top country singles. Urban earned seven ACM nominations including entertainer of the year and album of the year at this year's Academy of Country Music Awards. Urban also scored nominations for male vocalist of the year, single record of the year, and song of the year. The nominations were announced Thursday morning by country trio Lady Antebellum.
