Britney Spears: I do sing live and nobody ever gives me credit for it

“I’m glad you’re addressing this question because it’s really funny. A lot of people think that I don’t sing live. I do usually — because I’m dancing so much — I do have a little bit of playback, but there’s a mixture of my voice and the playback. It really pisses me off because I’m busting my ass out there and singing at the same time, and nobody ever really gives me credit for it. You know?”Britney Spears, in an Israeli TV interview. She was asked: “How much of your show is with playback — backed up with playback, how much of it is live?”
