The Country Music Association (CMA) has changed the criteria for three of its awards. On the 2005 ballot, the singles must have reached the Top 50 in either Billboard or Radio & Records for the first time during eligibility period. Previously, eligibility was based on the single’s release date. In the album category, the mastering no longer has to take place within the eligibility period. For the musician of the year, CMA members no longer need to name the product for which a musician is being nominated.
