Saw Coldplay at the Horden in 2003, liked Parachutes, throught Rush of Blood was OK. They were good live at that time. My girlfriend bought X+Y, and it still hasn't grown on me. $120 sounds a bit steep?
Saw them at Glastonbury a week after the CD came out, found their performance lacking in passion and energy compared to years before, and their new songs nothing to write home about. Wished I'd gone and watched The Proclaimers on another stage instead.
Radiohead are a world above Coldplay, even post-OK Computer. And live Radiohead are fantastic and passionate with their new material. At least they are putting out stuff that is interesting and different to what they did before, rather than Rush Of Blood part 2...
