Grammys Chief Harvey Mason Jr. has praised Beyonce's ability to cross genres with her music.
Beyonce is among the nominees in the Best Album and Best Country Album categories for 'Cowboy Carter' - the country-inspired record that she released earlier this year - while 'Texas Hold 'Em' has been nominated for the Song of the Year accolade and Harvey says the nominations have "credibility" because they are voted for by experts in each category.
