"I'll stay with you/Till hell freezes over," Bernard Sumner intones on the ninth New Order album. Chances are he's not referring to his bandmates: Allegedly the final release from the massively influential dance-rock group's original lineup (bassist Peter Hook departed in 2007), Lost was cobbled of outtakes from its previous album, 2005's lackluster Waiting for the Siren's Call. Surprisingly, it's a much better record. The mesmeric dance-floor electronics on tracks such as "Shake It Up" recall Eighties classics like "Blue Monday," while Sumner's six-string chime and plangently defiant vocals make this accidental swan song feel industrial-grade wistful.

“1999”

“I don’t consider myself a great poet,” Prince told Rolling Stone. “I just know I’m here to say what’s on my mind.” In the case of the apocalyptic party anthem “1999,” he was worried about then-president Ronald Reagan’s foreign policies. The song’s melody is based on a riff borrowed from the Mamas and Papas’ “Monday, Monday,” and Prince originally envisioned the first verse with three-part harmony but later split the vocals between himself and members of the Revolution. Because Warner Bros., with whom Prince was locked in a contractual battle, owned the original’s masters, Prince rerecorded the song and appropriately released that version in 1999.
