“They’ll find me out. It’s like The Wizard of Oz. They’ll find out there’s nothing there. As for collaborations, I’m collaborating with the band and do what we do. I see myself as a member of this band who does these songs that we write.” ---Singer Sade was quoted before turning down rapper Jay-Z on a request for a collaboration. The singer has had a change of heart. It has been reported that the singer has requested that Jay-Z provide a rap verse for her track "Moon & Sky". The rapper Jay-Z has responded to this request and the remix of "Moon & Sky" will appear on Sade's greatest hits compilation, Ultimate Collection that's due in stores on May 3rd.
