I always thought a warning sign was the most underrated song but I see now a lot of people feel that way so it may not be. whenever i'm stressed i listen to it and it calmes me down.
also trouble will always be my fave, since it was the first coldplay song I ever heard and immediatly made me fall in love.
the hardest part and X&Y should have been on top of the charts, but they just never took off. WHen X&Y came out I never thought these songs would become singles since they were the best songs on the album in my opinion, and in the past my faves never became singles
Sorry but I strongly disagree I think Life in technicolor is one of the greatest openers ever! and fits perfectly in line next to square one, the mystical build up is fabulous and it's a perfect little taste of what the rest of the album brings you, I also love that the escapist seemlesly crosses over and is the perfect ending to a perfect album.
i was just going to write a short answer....
