"I got 'em scared, shook, panickin'," Nicki Minaj boasts in her Eminem duet "Roman's Revenge," and anyone who's heard this one-of-a-kind MC knows she isn't kidding. Her mixtapes and guest shots made her massive — she totally stole Kanye West's "Monster," rhyming "Tonka," "Willy Wonka" and "bad bitch that came from Sri Lanka." On Pink Friday, the year's most anticipated hip-hop debut, she's already rapping about the superstar life. In the standout opener, "I'm the Best," she wonders, "Which world tour should I go on today?"

Friday is surprisingly pop — there's nothing as weird or striking as her "Monster" cameo. Instead, Minaj aims for a Rihanna-style crossover approach, singing R&B choruses over electro floss and toning down her nasty side. Ri herself guests on "Fly," while Natasha Bedingfield does the hook-girl honors on "Last Chance." "Blazin" is a Kanye rematch, except this time he gets all the best lines (especially "I got two White Russians, but we also need some drinks").

“Oh Sherrie”

Steve Perry's girlfriend Sherrie Swafford was actually in the studio when Perry began writing this song--his lone Top Ten hit as a solo act--with two co-writers. The trio began at midnight one night with just "Oh, Sherrie!" and "hold on, hold on." Three hours later, they had a complete song. Swafford, however, had to wait until the next day to hear it. "Sherrie actually got tired and went to bed," Perry said. She also appeared in the video, but their relationship did not hold on for long.
