They need to kick Max Martin out
His fingerprints are clear on every body of work he touches, and they are an ugly fit on Coldplay's sound. His production doesn't play to their strengths at all and to me sort of neuters their sound and makes it just that bit more generic. They need to fire the guy—they have a ton of producers they already work with well and could work with: they're Coldplay for goodness' sakes.
