Jessie J is no girly girl — she's a Brit newcomer who wears her hat low and often avoids pants. The 22-year-old already has a sugary hit on her resume (she co-penned Miley's "Party in the U.S.A."), but on her debut single she her stomps her way across the pond, presumably with tongue in cheek: "Do It Like a Dude" finds her grabbing her crotch and dropping MF-bombs over rock riffs while calling her girls "sugar" and throwing in a brawling pop chorus. Fierce!

“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.
