That hasn't stopped the band becoming the biggest of the century; and Mylo Xyloto is unlikely to lose them any fans.
The album was apparently inspired by graffiti and an anti-Nazi movement, but it feels mostly optimistic, not angry.
Tracks are split pretty evenly into irresistibly bouncy numbers like Hurts Like Heaven, Charlie Brown and lead single Every Teardrop is a Waterfall, and more pensive, dreamy offerings.
The first of these, Paradise, combines soaring strings, Morse-code-like beeps and the clearest lyrics on the album. But it also highlights the album's - and maybe the band's - biggest weakness: a tendency to fill bars with broken-up words and "ooooh aaahhh whoooaaahh"s.
Highlights include Major Minus and its gritty bass, like something the Beatles might have written in the Come Together days; and UFO which, despite the sci-fi title, is a heartfelt acoustic ballad.
If you just don't like pop-rock, there's nothing here to convert you. But if you're open to the idea of rockers being softies, go with Coldplay to their happy place.
