I am probably on my own in ranking AROBTTH as 3rd best album, and Parachutes 4th, but that's beside the point.
I agree that AROBTTH and Parachutes are probably the best albums lyrically, but I think the sound of X&Y and VLV at times is unrivalled. Yes, Yellow and The Scientist are as good as Coldplay have got musically, but I think the music on X&Y and VLV is more consistent. Consistently brilliant, that is.
