The big story of the 2018 Grammys? The ceremony is finally getting serious about hip-hop. The awards have always had a strange history with rap, going back to the Eighties, when the voters were convinced (along with most of the music industry) that all this rap stuff the kids were into was a fad. For years, hip-hop artists were allowed to play but not to take home trophies. But this year, all major categories are dominated by rap. Album and Record of the Year are both Kendrick Lamar vs. Jay-Z battles, along with surprise nominee Childish Gambino. From MC Hammer to Lauryn Hill to ODB, here's a timeline of how far hip-hop has come at the ceremony.
