Por cierto, Ryan Tedder ha concedido una entrevista a The Guardian y le han preguntado si Beyoncé compone o no: http://www.theguardian.com/music/2014/apr/23/ryan-tedder-one-direction-one-republic-harry-styles
Your original demo version of Beyoncé's Halo is online and, production aside, it's pretty similar to the finished version. People have accused her in the past of adding her name to a song's credits â can you shed any light on that?
I can't speak for all of the songs that she does but I'll say this: she does stuff on any given song that, when you go from the demo to the final version, takes it to another level that you never would have thought of as the writer. For instance, on Halo, that bridge on her version is completely different to my original one. Basically, she came in, ditched that, edited it, did her vocal thing on it and now it's become one of my favourite parts of the song. The whole melody, she wrote it spontaneously in the studio. So her credit on that song stems from that. In terms of her other songs, I can't say. I know there's a long history, whether it's Céline Dion or Whitney, of artists transcending being just artists and becoming icons. Can they demand more? Absolutely. Whether you agree with it or not, they can because they can.
