No Doubt Ready To Rock Steady (From MTV.com) relevant quotes are below.

CULVER CITY, California -- No Doubt might as well change their name to No Rules for their upcoming album.

Rock Steady, due December 18, is a scattered collection of pop, rock, rap and reggae songs produced by everyone from Prince to Dr. Dre. Prince's effort, "Waiting Room," stems from sessions for last year's Return of Saturn, which featured the hit "Simple Kind of Life." The Artist, as he was then known, duetted with Stefani on his 1999 album Rave Un2 the Joy Fantastic and promised to return the favor by producing a track for No Doubt.

"We sent him and a demo and ... it's so funny how things work out," Stefani recalled. "We fly in and get off the plane and someone hands me a phone and says, 'Prince needs to talk to you.' He's like, 'I had to rewrite it. You're going to like it.' He rewrote the whole thing, sang it, played on it, everything. It didn't fit anywhere on Saturn, but it fits perfectly on this one. I re-sang my vocals, we added stuff and made it No Doubty."
