August 28th of this year was the 50th anniversary of Dr. Martin Luther King, Jr.'s historic "I Have A Dream" speech in Washington D.C. And this week, we again will celebrate King's contributions to social and political change with a federal holiday in his name.

Over the years, the music world has also been inspired by his life and work, and the staff at Billboard picked our 10 favorites among those songs, from the obvious (U2's Pride (In The Name Of Love), to another from the band "MLK", to the unfettered optimism of Springsteen's "We Shall Overcome."
