Already a nine-time Grammy Award winner, R&B-soul singer-songwriter John Legend is having a banner year with a Grammy for Best Pop Solo Performance for his chart-topping composition "All of Me (Live)," a song he wrote for his new wife, fashion model Chrissy Teigen. He's also nominated for Best Rap Song as a co-writer for frequent collaborator Kanye West's "Bound 2" from the rapper's extolled sixth album, "Yeezus."

Thanks to the Academy of Motion Picture Arts and Sciences, he's also up for the Academy Award for Best Original Song for "Glory," the theme song for Ava DuVernay's historical drama "Selma." The film -- based on the 1965 Selma to Montgomery voting rights marches led by James Bevel, Hosea Williams, John Lewis of SNCC and Martin Luther King Jr. of SCLC -- follows the civil rights leaders' conflicts leading up to 1965's Voting Rights Act.

Legend and his collaborator, iconic rapper Common, will also perform "Glory" at the 57th Annual Grammy Awards on Sunday, Feb. 8. The hip-hop ballad "Glory" won a Golden Globe Award for Best Original Song over the universally celebrated "Everything Is Awesome" by Tegan & Sara and The Lonely Island from the commercially successful computer animated adventure comedy "The Lego Movie," thanks to the Hollywood Foreign Press Association. This marks Legend and Common's first times being nominated in the category.

"I'm grateful for all of them," Legend said of his accomplishments in an interview with USA Today. "But I think it's a little extra special for the Golden Globes and the Oscars, as a musician ... at this point in my career."

Legend noted that "Glory" hold special place in his heart as it was inspired not only by "the work of Dr. King and so many others who fought for justice," but by their beneficiaries, hinting at the demonstrators behind the Black Lives Matter movement, the protests in Ferguson, Missouri and the death of Eric Garner at the hands of police officers in Staten Island, New York. "We still see people, young and old, of all races, protesting in the street, saying that black lives matter in this country -- that we believe in equality in this country."

"I was on the road the whole time," Legend said, noting that he did not take part in the intense protests that followed after grand juries neglected to provide indictments against the officers involved of both Garner and Mike Brown cases. "But I donated food, and I sent money to organizations mobilizing young people."

Following in the efforts of Harry Belafonte, the actor-singer and civil rights activist, Legend noted: "Every artist has to make an individual decision. Some may know what to say; they may be frustrated but not as educated. There could also a be fear of commercial repercussions if they say the wrong thing... I've always believed there's nothing wrong with an artist telling the truth, using the platform to promote justice and spread love."

He added: "People have told me they sing it at their weddings, or have someone sing it at their weddings." Feeling "honored," Legend declared, that "I made a song that was about my own relationship ... that other people could feel it as well, and apply it to their own relationship."
