"Over the Rainbow" it ain't. Still, the theme song from Disney's The Wizard of Oz prequel, Oz the Great and Powerful, has its modest virtues: an instant earworm chorus, deft production by Stargate and, just where you'd expect them (on the other side of the third chorus), some flamboyant vocal runs from Ms. Carey.

“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.
