Mandela: the three syllables not only refer to the legendary anti-apartheid leader and former President of South Africa, but serve as a modern synonym for equality, freedom and revolution. Nelson Mandela's legacy continues to endure in hearts and history books, and his ideals will continue to serve as inspiration in popular music. 
 
 Mandela's Death: Artists React on Twitter | Bono Pens Moving Essay 
 
 Today (Dec. 5), the iconic figure died at 95 in his Johannesburg home with his family at his side. From Public Enemy to Youssou N'Dour to Santana to U2, some of music's biggest stars have tipped their caps to the revered statesman in their songs, albums and even poems. Check out these 10 particularly memorable musician tributes to Nelson Mandela: 
 
 U2, "Ordinary Love" 
 
 U2 made this heartfelt song for the newly released film "Mandela: Long Walk To Freedom," a biopic on the man himself. When "Ordinary Love" dropped weeks ago, it was first new material from the rock band since 2010's "Soon," premiered on the "U2 360 at the Rose Bowl" soundtrack. With lyrics like, "We cannot reach any higher/ If we can't feel ordinary love," Bono tried to embody what Mandela stood for. 
 
 Hugh Masekela, "Mandela (Bring Him Back Home)" 
 
 Masekela, a Grammy-nominated jazz musician from South Africa, recorded this track in 1987, and sings that he "wants to see him (Mandela) walking down the streets of South Africa tomorrow." 
 
 The Special A.K.A., "Free Nelson Mandela" 
 
 Unlike most protest songs, "Free Nelson Mandela" moves to a celebratory beat and a cheerful chorus -- but the message is still a plea for the imprisoned Mandela to be released. "His body abused, but his mind still free" is sung of Mandela, who had been serving 21 years in prison at the time the song was written. Produced by Elvis Costello, the single was performed on the "Top of the Pops" in 1984. 
 
 Youssou N'Dour, "Nelson Mandela" 
 
 N'Dour is one of Senegal's most famous cultural icons, and his genre-bending repertoire has found him collaborating with Peter Gabriel, Bruce Springsteen, and Wyclef Jean. In 1986, N'Dour released an album entitled "Nelson Mandela," as a tribute to the future President of South Africa. 
 
 Public Enemy, "Prophets of Rage" 
 
 One of the most influential hip-hop groups in history, Public Enemy was never short on righteous political messages -- and it should be no surprise that one of their most iconic tracks name-checked Mandela. In "Prophets of Rage," Chuck D raps "We have a reason why to debate the hate," while Mandela is mentioned in the company of other prominent leaders in the anti-segregation movement. 
 
 Santana, "Mandela" 
 
 Unlike most tribute songs in pop, this1988 Carlos Santana cut was written as an instrumental, and was also performed at Mandela's 70th Birthday Celebration. The song obviously does not nod to Mandela explicitly, the unmistakable guitar tone and Latin percussion act as an enduring paean from the multi-platinum musician. 
 
 Simple Minds, "Mandela Day" 
 
 Simple Minds is best remembered for its 1985 hit "Don't You (Forget About Me)," which became a classic after it was used in the "Brat Pack" favorite "The Breakfast Club." Three years later, the group performed this tribute track at Mandela's 70th Birthday Celebration at Wembley Stadium. The song served as a banner of hope as the band sang, "The tears are flowing wipe them from your face I can feel his heartbeat moving deep inside." 
 
 2pac, "Just a Breath of Freedom (4 Nelson Mandela)" 
 
 Tupac Shakur's poem acts as a letter of praise to Mandela for his decades of struggle in the name of equal rights. "Held captive 4 your politics/ They wanted 2 break your soul/ They ordered the extermination of all minds they couldn't control," Pac writes about Mandela's journey. 
 
 Tracy Chapman, "Freedom Now" 
 
 Soon after Tracy Chapman rose to fame for her No. 1 self-titled album in 1988, she found herself writing and performing this Mandela protest song at his 70th Birthday Celebration. A constant spokeswoman for social change, Chapman's song speaks against a society that kills and destroys that which it doesn't understand. The most memorable verse from the track reads, "Soon must come the day/ When the righteous have their way/ Unjustly tried are free/And people live in peace I say/ Give the man release/ Go on and set your conscience free/ Right the wrongs you made/ Even a fool can have his day." 
 
 Johnny Clegg, "Asimbonanga" 
 
 Written as a mix of Zulu and English, the title of this Mandela freedom track is Zulu for "We have not seen him"; at that point, no one had seen Mandela outside of prison for more than two decades. Hailing from South Africa, Clegg stirred up controversy for not only writing this protest hit, but for also having bandmates of different races during the days of Apartheid. In 1999, the band was joined onstage by Mandela during a performance of "Asimbonanga." ||||| President Barack Obama Thursday eulogized Nelson Mandela as “a man who took history in his hands and bent the arc of the moral universe toward justice.” 
 
 Obama, speaking shortly after South African President Jacob Zuma announced Mandela’s death, called the man for so long known as Prisoner 46664 as “one of the most influential, courageous and profoundly good human beings that any of us will share time with on this earth.”

 “We will not likely see the likes of Nelson Mandela again — so it falls to us as best we can to forward the example that he set: to make decisions guided not by hate, but by love, to never discount the difference that one person can make, to strive for a future that is worthy of his sacrifice.”

 The president is expected to travel to South Africa for the state funeral, which has not yet been scheduled. National security staff told Obama in the Oval Office of Mandela’s death shortly before 5 p.m. EST, White House officials said. 
 
 Obama ordered American flags lowered to half staff through Monday in recognition that “the United States has lost a close friend, South Africa has lost an incomparable liberator, and the world has lost an inspiration for freedom, justice, and human dignity.” 
 
 He reiterated these sentiments to Zuma in a phone call Thursday evening, offering his condolences on behalf of the nation, and speaking of “how profoundly Mandela’s extraordinary example of moral courage, kindness, and humility influenced his own life” and of the deep relationship between the United States and South Africa, the White House said.

 Mandela is the father of modern South Africa, and Obama addressed part of his remarks to the people of that nation as well, praising them for being an example to the world of “renewal and reconciliation and resilience.” 
 
 Beginning his statement at the White House by reading a quote from Mandela, the president spoke for just a few minutes, reflecting on Mandela’s impact on the world — and on him personally. Obama spoke of how reading Mandela shaped his thinking about who he was and who would want to be, recalling that his own entry into politics was a speech at an anti-apartheid, South African divestment rally. 
 
 “I am one of the countless millions who drew inspirations from Nelson Mandela’s life,” Obama said. “I cannot fully imagine my own life without the example that Nelson Mandela set. So long as I live, I will do what I can to learn from him.” 
 
 The two met just once, and briefly — in Washington in 2005, when the just-elected Senator Obama pushed for a meeting with the former president, and was initially rebuffed — but did produce a well-known photo of Obama leaning over a seated Mandela, holding his hand, one in the shadow, one in the light. 
 
 Obama did not meet with him when he traveled to South Africa a year later, but Mandela sent Obama a letter after his election calling it a measure of what was possible in the world, and the two spoke occasionally over the phone in the years since. 
 
 A Mandela health scare halted plans for a possible meeting when Obama returned to South Africa this past summer. But Obama visited Mandela’s old cell at Robben Island and met with Mandela’s family, and in a speech while in the country, praised the leader for showing “us that one man’s courage can move the world.” 
 
 Carrie Budoff Brown contributed. ||||| Counting himself among the millions influenced by Nelson Mandela, President Barack Obama on Thursday mourned the death of the anti-apartheid icon with whom he shares the distinction of being his nation's first black president. 
 
 "He no longer belongs to us. He belongs to the ages," Obama said in a somber appearance at the White House. 
 
 "I am one of the countless millions who drew inspiration from Nelson Mandela's life," he continued. "And like so many around the globe, I cannot fully imagine my own life without the example that Nelson Mandela set." 
 
 Mandela died earlier Thursday at 95. He had spent much of the year in and out of the hospital, and his illness prevented a meeting with Obama when the U.S. president visited South Africa this summer. 
 
 However, the former South African president's legacy hung over Obama's trip. The U.S. president made an emotional visit with his wife, Michelle, and two young daughters to the prison at Robben Island, where Mandela was in captivity. The Obamas also met privately with members of Mandela's family.
– President Obama today paid homage to Nelson Mandela shortly after the former South African leader's death was announced, reports Politico and AP. "He no longer belongs to us," said Obama. "He belongs to the ages." Some other highlights: Mandela was “a man who took history in his hands and bent the arc of the moral universe toward justice.” “We will not likely see the likes of Nelson Mandela again—so it falls to us as best we can to forward the example that he set: to make decisions guided not by hate, but by love, to never discount the difference that one person can make, to strive for a future that is worthy of his sacrifice." “I cannot fully imagine my own life without the example that Nelson Mandela set. So long as I live, I will do what I can to learn from him.” Other tributes: Music: Billboard rounds up 10 musical salutes to Mandela, from Bono to Public Enemy.
