"We're broken people living on the loaded gun," Linkin Park cry over clattering keyboards on lead single "The Catalyst," which suggests a scream-y Depeche Mode. With Rick Rubin co-producing, the band embraces not just synth-pop clamor but also dancehall-style chants and U2's grandiosity. It's the sound of Linkin Park feeling their way toward a new identity, but their skill for melody is obvious. And on the rap-rock "Wretches and Kings," they sound like a killer Linkin Park tribute band.

“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.
