Okay, it's rather common knowledge around here that I don't like Coldplay at all these days. At all. But those songs that you mentioned are probably the only songs of theirs that I can tolerate. I bought Parachutes shortly after it first came out and was very interested by Trouble and Spies. Spies in particular. It had a very interesting sound...kind of U2-ish, but not overly so. There was a little something of their own in there. It was a haunting, mysterious sound, and it sounded good. I sometimes even listen to it every now and then for the hell of it (I threw away AROBTTH and downloaded X&Y). I honestly think that Parachutes is the only album that features some form of originality by Coldplay. And Trouble is just so damn mournful, a beautiful song with a cool video to boot.
When AROBTTH came out, I began to lose interest. Then when some of their new songs became emerging, like "Moses," I just got turned off from them completely. I can't respect a band that resorts to blatant rip-offs. I know that's not why you're disappointed in them, but it's why I am.
And I agree with you 100% on your analysis of X&Y. That album is not nearly worth the hype it's receiving. It's the sound of Coldplay regressing even further, borrowing even more from other bands, and just losing ideas in general. Certainly doesn't sound like progress to me, as some fans like to call it. And really, could someone tell me why all the songs on it sound the fucking same? Or why Jon Buckland has suddenly decided he is The Edge? X&Y, to me, is nothing more than the endless drone of shit.
