'Mississippi Goddam,' Nina Simone

Although many of Nina Simone's songs from the 1960s capture the spirit of the civil rights movement, "Mississippi Goddam" and "I Wish I Knew How It Would Feel to Be Free" could be the sound track to the era because of their ability to touch on the remarkable human drama that made the 1960s a revolutionary time.
