Before Sunday the Grammys had frequently shut out hip-hop artists from its top prizes, despite rap's dominance as the biggest music genre in the United States.

Only two albums by hip-hop artists have ever won the album of the year Grammy - Lauryn Hill's "The Miseducation of Lauryn Hill" in 1999, and Outkast's "Speakerboxxx/The Love Below" in 2004.

Musgraves also won for best country album, song and country solo performance.

This year's Grammy nominees were dominated by women and the awards show, hosted by Alicia Keys, reflected that with rousing performances by Lady Gaga, Cardi B, Jennifer Lopez, Diana Ross, Dolly Parton, Miley Cyrus, Janelle Monae, Katy Perry and Musgraves.
