U2 - Sunday Bloody Sunday (1983)

 "Sunday Bloody Sunday" is noted for its militaristic drumbeat, harsh guitar, and melodic harmonies. One of U2's most overtly political songs, its lyrics describe the horror felt by an observer of the Troubles in Northern Ireland, mainly focusing on the 1972 Bloody Sunday incident in Derry where British troops shot and killed unarmed civil rights protesters. Along with "New Year's Day," the song helped U2 reach a wider listening audience. It was generally well received by critics on the album's release.

The song has remained a staple of U2's live concerts. During its earliest performances, the song created controversy. Lead singer Bono reasserted the song's anti-sectarian-violence message to his audience for many years.

Today, it is considered one of U2's signature songs, and is one of the band's most performed tracks. Critics rate it among the best political protest songs and it has been covered by over a dozen artists. It was named the 272nd-greatest song by Rolling Stone on their list of "The 500 Greatest Songs of All Time."
