THOUGH Black Out Tuesday was originally organized by the music community, the social media world also went dark in support of the Black Lives Matter movement, joining voices around the world outraged by the killings of black people in the U.S.

Instagram and Twitter accounts, from top record label to everyday people, were full of black squares posted in response to the deaths of George Floyd, Ahmaud Arbery and Breonna Taylor.

Most of the captions were blank, though some posted #TheShowMustBePaused, black heart emojis or encouraged people to vote Tuesday with seven states and the District of Columbia are hosting the largest slate of U.S. presidential primary elections in almost three months.

Rihanna, Alicia Keys, Radiohead, Coldplay, Kelly Rowland, and Beastie Boys were among the celebrities to join Black Out Tuesday on social media.

Spotify blacked out the artwork for several of its popular playlists, including RapCaviar and Today’s Top Hits, simply writing “Black lives matter” as its description. The streaming service also put its Black Lives Matter play-list on its front page, featuring songs like James Brown’s “Say It Loud — I’m Black and I’m Proud,” N.W.A.’s “(Expletive) the Police,” Sam Cooke’s “A Change Is Gonna Come” and Childish Gambino’s “This Is America.”

The opening pages of Apple Music and iTunes focused on supporting Black Lives Matter, and SiriusXM said it will be silencing its music channels for three minutes at 3 p.m. EDT in tribute to “all of the countless victims of racism.”

The company said it “will continue to amplify Black voices by being a space where Black artists showcase their music and talents, and by carrying the message that racism will not be tolerated.”

Several music releases and events were postponed as a result of Black Out Tuesday. Interscope Geffen A&M Records said it would not release music this week and pushed back releases from MGK, 6lack, Jessie Ware, Smokepurp and others. Chloe x Halle said its sophomore album will come out June 12 instead of Friday, while the group Glass Animals postponed the Tuesday release of its new single “Heat Waves.” Instead of being released Wednesday, singer Ashnikko will drop her song “Cry” and its video June 17.
