"It's definitely open for interpretation," he told MTV News. "I'm really excited about 'Shake.' We decided that would be the first single to represent Have It All and ... I felt like that song was kind of the closest to [2008's] Departure and it was a way to sort of reacquaint the fans with my music."
Back when McCartney released Departure, the singer touched on sexier R&B tracks, proving that as he grew out of his sugary, sweet, teen-pop image he was willing and unafraid to make music that was meant for listeners of all ages. And, "Shake" is certainly even more mature. "It's a kind of ... urban, kitschy track with a lot of synths and pop melodies on top, and it makes for good ear candy," McCartney explained. "And I think a good out-of-the-gate single, and the fans — I've been on tour for a couple of weeks [and] the reaction's been incredible from them."
Next up, McCartney plans on shooting an equally glossy video for the track. "So I'm gonna shoot a video when I get back to L.A. in about a week and I'm gonna be working with Fly, my choreographer, and we're gonna get a few dancers, a few girls to be in the video," he teased. "It's gonna be cool. We wanted to create a video that wasn't necessarily a story, following the song. It didn't necessarily have to be on the nose. We wanted something that was visually stimulating, a lot of cool camera techniques that haven't been used, a lot of saturated colors. So I'm excited about that too. The fans should have that in a few weeks."
