Firstly, it isn't up to me to do your research for you. It's your information that you seem determined to insert prominently near the top of the article, so the burden is on you to provide proper cited sources for it. I already made my contribution: I prefer to just jettison the entire paragraph, as I already did, or at least move it somewhere much lower in the article. Secondly, some of the stuff you just mentioned are still various rock critics giving their own opinions of "obvious" influences. To say "Coldplay is influenced by Oasis", we need a source with an actual band member stating words to this effect. Thirdly, why is it so important to you to devote so much time, space, and effort to Coldplay's influences, and why is it important enough to be so near the top of the article?
