Sad night in the music world: Leonard Cohen has died at age 82, according to an announcement on his Facebook page. "We have lost one of music’s most revered and prolific visionaries," it reads. A tribute at Rolling Stone agrees with that sentiment, saying that only Bob Dylan has had a greater influence among the classic songwriters to emerge from the 1960s and '70s: "Cohen's haunting bass voice, nylon-stringed guitar patterns, Greek-chorus backing vocals shaped evocative songs that dealt with love and hate, sex and spirituality, war and peace, ecstasy and depression." One of his most covered songs is "Hallelujah." No details about the cause of death were released. (In a recent New Yorker profile, Cohen said he was winding down and putting his house in order.)
