I am a huge U2 fan, and I am a huge Coldplay fan primarily because of VLVODAAHF, which reminds me a decent bit of U2's The Unforgettable Fire. They are both two of my all-time favorite albums. However, Viva la Vida is a different album than TUF, and I can tell that they are going in a different direction and are Coldplay, not U2. I love both bands, and they are similar, but different in their musical style in direction.
