Eminem has joined the cause.

The 47-year-old rapper announced that his music studio, Shady Records, will be participating in the #BlackoutTuesday campaign, a movement that started within the music industry to symbolize standing against racial injustice. The day has been widely accepted by the public and other businesses, many of whom are posting plain black squares on their social-media pages to support the Black Lives Matter movement.

“We will be closed on Black Out Tuesday. Join us in fighting for change,” the New York City-based record company wrote on Twitter. “On this day we will dedicate our time and efforts to help prevent social injustice and explore ways to assist in the fight against racial inequality.”

A graphic included in the post urges fans to donate to the NAACP, the Southern Poverty Law Center and Black Lives Matter, as well as sign petitions “in support of justice” for Breonna Taylor, George Floyd and Ahmaud Arbery.

Artists including Bad Meets Evil, D12, Slaughterhouse and Yelawolf are signed with Shady.

But not all in the music industry think #BlackoutTuesday is an effective way to contribute to the social movement.

“I don’t think the movement has ever been this powerful. We don’t need to slow it down by posting nothing. We need to spread info and be as loud as ever,” wrote Lil Nas X on Twitter.

Some community leaders are upset that those posting black squares to signal their support with #BlackoutTuesday are using the hashtag #BlackLivesMatter.

“When you post your black square please don’t use the hashtag #BlackLivesMatter,” said Lizzo in an Instagram video. “It is flooding the hashtag search with just black pictures instead of information.”

Kehlani also posted about the danger of the blackout on the hashtag. “when people click that hashtag, they need to see what’s going on. they need to see it harshly, vividly, accurately, in their faces,” she wrote on Twitter.
