For a 17-year-old YouTube champ with a co-sign from Kanye West (who refashioned the Chicago rapper's viral hit "I Don't Like" for radio), Chief Keef is weirdly lacking in irony. Beyond "I Don't Like," which inverts the Facebook thumbs-up for snitches and shitty weed, his label debut hops from one homely declaration to the next, whether it's "Hate Bein' Sober" (with a bemused 50 Cent and Wiz Khalifa) or "Laughin' to the Bank," with its hollow "ha ha ha" punctuation. Rapping with his affectless slur and bricklayer's tempo over rolling, mid-speed beats, Keef (who was criticized for mocking a murder victim, his rival, on Twitter) seems unshakably confident but profoundly directionless. The effect is mesmerizing, and a little scary.

Listen to 'Finally Rich':

“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.
