By album: Parachutes: "We Never Change", so simplistic but allows the band's talent to show through without any distractions. Rush of Blood...: Amsterdam, although i do also love the acoustic "In My Place" i found elsewhere. Off of what I've heard of X&Y "White Shadows" is leading for me, im not as impressed by "A Message" as everyone else is for some reason.... and a wildcard b-sides song, "High and Low." Even though it isnt really a Coldplay song i can seriously just listen to it over and over again if i ever need to calm down completely
