"Angel of Harlem" is a song by Irish rock band U2. It is the tenth track on their 1988 studio album Rattle and Hum, and was released as its second single in December 1988. It topped the charts in Canada and New Zealand, and peaked at number nine on the UK Singles Chart, number eight on the Dutch Top 40, number 14 on the Billboard Hot 100, and number one on the Mainstream Rock Tracks chart. Written as a homage to Billie Holiday, it was released with two different B-sides; one was an original U2 song called "A Room at the Heartbreak Hotel," while the other was a live version of Rattle and Hum's "Love Rescue Me".
It also has nothing to do with the cache, except that the song was playing on the radio when I hid it.
