13. "Every Breaking Wave"
Fourteen years after "Sunday Bloody Sunday," U2 released their second single to address the sectarian conflict in Northern Ireland (Mullen's drumming on the bridge even seems to allude to the 1983 hit). Producer Howie B, who Mullen called U2's "disco guru," had taken the band to dance clubs to help usher in their electronica experiment Pop. For "Please," he played them a beat rooted in a loop of Mullen's drums from the sessions for another Pop tune, "If God Will Send His Angels." Bono constructed a melody, and the song promptly fell into place. "Once the band got it, boom," said Howie B. Bono called it "a mad prayer of a tune."
