Tuesday was country crooner Toby Keith's lucky day. He leads this year's nominations for the Country Music Association Awards with seven nods, including best entertainer, male vocalist, and album of the year for Unleashed. Johnny Cash snagged four CMA nods — two for his cover of the Nine Inch Nails song "Hurt." Brooks &#038 Dunn and Brad Paisley also received four each. And despite all their Dubya drama this year, the Dixie Chicks still got two nods, including best album for Home.
