Come on! It's such a bog-standard melody and chord progression to start with! The same four chords, over and over. Took me about 3 seconds to work out how to play the song, or songs, as it turns out, in their entirety. I really don't care too much what happens to Coldplay either way, but really, this is the entire INDUSTRY, guys. The whole thing is built on obvious melodies, and major-relative minor-dominant-subdominant chord progressions in various keys/permutations, which means that this sort of 'plaigarism' thing is bound to happen all the time. Which, of course, it does.
