Poor Coldplay...
They sure do sound similar, fair enough. I think it's fair of Joe to sue, if he wants to, but maybe a retroactive credit would be a just decision, as in the case of KD Lang and Rolling Stones. After all, aside from the poached melody, the songs really aren't the same.
As a mild Coldplay fan, i surely don't wish their songs had never been created - it's just a shame to find out they aren't 100% unique. And it makes me wonder why the band has invested so much airtime into proclaiming their revolutionary, cutting-edge status...
On a side note, what if we've simply come to the point where there is no unique music left, it's all been written? All we'll be left with is rehashings of the same old thing...it will be like the musical version of the film Maid in Manhattan.
