To celebrate United Nations Human Rights Day on Thursday (Dec. 10), John Legend received the prestigious High Note Global Prize for social justice, presented by United Nations Human Rights, partner of the High Note Global Initiative and David Clark Cause.

The award honors recording artists who use their music and platform to promote social justice and positive change. Legend is an outspoken advocate for prison reform, voters' rights, healthcare, equality and education, among other causes.

“I believe in the power of music to inspire us, to connect our hearts, to give voice to feelings for which words alone won’t suffice, to wake us up out of complacency, to galvanize and fuel social movements," the singer said upon accepting his award. "Artists have a rich tradition of activism. We have a unique opportunity to reach people where they are, beyond political divisions, borders, and silos. And it’s been my privilege to use my voice and my platform to advance the cause of equity and justice."

He went on to highlight his most recent campaign, #FreeAmerica, which works toward criminal justice reform. "As a citizen of the United States, and of the world, I know that for far too long our most essential systems have served to perpetuate inequity and injustice," he shared. "In order for us to create a just world those systems need to change."

"With this award we celebrate a multitude of advocates, generations of movement leaders who have put their shoulder to the wheel of progress," he concluded. "I don’t stand here absorbing these accolades for myself. I stand here grateful for their ideas and their energy and honored that I can amplify their voices by using my platform."
