The conversation around music has never been as expansive and exciting as it has been in 2019. Pop resembled R&B and rap resembled pop, while Latin music became much, much bigger than Latin America: Artists weren’t dismantling conventions and boundaries this year so much as they were completely ignoring them, conjuring vital new sounds in the process. Billie Eilish made us simultaneously reconsider the definitions of pop and alternative, and Lil Nas X rode his horse down “Old Town Road” all the way to the top of the charts. OASIS brought together J Balvin and Bad Bunny, while Ed Sheeran pitched an enormous tent for No.6 Collaborations Project, inviting everyone from Cardi B to Chris Stapleton, H.E.R. to Eminem to Travis Scott and Justin Bieber, with whom he recorded the dancehall-influenced smash “I Don’t Care.” And women didn’t just run hip-hop in 2019 (see: the splendor of Megan Thee Stallion and “Hot Girl Summer”), but they took over Nashville too, with artists like Maren Morris enjoying even-bigger-breakthroughs. Relive all of these moments and movements—across all genres and with artists from around the world—through this exclusive playlist of our picks for best of the year.
