He didn't produce Complicated.

And yeah, Martin's fingerprints are all over Complicated. I don't mind him writing with BJ, but much like Desmond Child, you can pretty much tell when he was involved with the writing (Desmond recycled the rhythm structure of Bad Name so often it's not even funny - so most of the points raised in the video aren't exactly new). Not so much with Taylor Swift, who always hires a dozen of other writing doctors as well, but that's hardly an accomplishment.

I like his writing for/with Pink, though. It almost sounds like his least diluted work (which makes sense, she tends to use less cowriters), but her attitude and voice makes it work.
