Voyager, in case it's ever encountered by extraterrestrials, is carrying photos of life on earth, greetings in fifty-five languages, and a collection of music from Gregorian chant to Chuck Berry, including "Dark Was the Night, Cold Was the Ground" by 1920s bluesman Blind Willie Johnson, whose stepmother blinded him at seven by throwing lye in his eyes after his father beat her for being with another man. He died penniless of pneumonia after sleeping bundled in wet newspapers in the ruins of his house that burned down, but his music just left the solar system.
