NEW YORK - R&B artist Bruno Mars won the top prize at the Grammy Awards on Sunday (Jan 28), denying rappers Kendrick Lamar and Jay-Z the honour of becoming the first hip-hop artist in 14 years to win the coveted album of the year award.
Mars won six Grammys including song of the year for his hit single "That's What I Like", and both record and album of the year for "24K Magic".
Lamar, 30, regarded as one of the most innovative rappers of his generation, won five prizes mostly in rap categories, for his album "DAMN." and single "Humble".
Lamar's victories came at the expense of veteran Jay-Z and his soul-baring album "4:44". Jay-Z won none of his eight nominations and chose not to perform at the three-hour show.
Rap last year surpassed rock as the dominant genre in US music.
On the red carpet, dozens of musicians wore or held white roses to signal support for women's equality and freedom from sexual harassment, a theme that was echoed on stage in an emotional performance by Kesha of her single "Praying".
