On No Doubt's M.I.A.-tinged comeback hit, "Settle Down," Gwen Stefani reminded us how a true food-court princess gets down. The band calls this Diplo-produced track its "Bohemian Rhapsody." It stacks SoCal ska, a big alt-rock chorus, dancehall flow and electro undergroove until it sounds like two and a half No Doubt songs at once. Luckily, Gwen's beach-blanket B-girl flow ("Speeding it up like soca/ ...On another level like we doin' yoga") holds this down to earth.

Listen to "Push and Shove":

“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.
