Mylo Xyloto was great imo.
A few points ;
HLH. CB. UATW. DLIBY, UWTB are some of Coldplay's best songs.
ETIAW is a great single and can always cheer you up.
Paradise was good until it became too overplayed on the radio.
The interludes are great particularly MX and AHT.
Major Minus is boring and I'm not too big a fan of UFO.
I still wish they could of made an atmospheric album like Viva la Vida again though. In fact I wouldn't of minded if they called the album Viva la Vida 2 :P MX is my 4th favourite album ahead of Parachutes, but I think that's more due to the fact that Coldplay have set such a high standard for themselves, meaning a really good album like MX is still their 4th best album!
