J.R. has worked with everyone from Britney Spears to Beyonce Knowles, but he says that no one needs to change up their sound more than Christina. Find out why!

J.R. Rotem has worked with the creme de la creme of female artists; he’s the man responsible for creating Beyonce’s super-hit “Survivor” and Britney Spears’ “Everybody.” So given his expertise, we were surprised to hear that he thought Christina Aguilera was the artist most in need of a revamp. But why?

“If I was working on Christina’s album, I would try to focus on an album that isn’t doing the dance music. I’d give her timeless songs that showcase her voice. Her forte is her voice,” the super-producer, who’s currently working with Nikki Minaj and Jason Derulo, explained toHollywoodLife.com exclusively during a phone chat. “She can sing anything, but her shining in the best light would be more timeless songs.

Don’t get him wrong — he loves the 29-year-old singer — so this definitely isn’t a criticism! “I’m a huge fan of Christina Aguilera’s voice!” he assures us. “She’s in her own lane — but she should be in more of a Whitney Houston and Mariah Carey virtuoso vocalists lane.”
