Challenge accepted! 4/6 with computer and a good set of grado labs headphones. But F me that Coldplay track was horribly mastered and compressed to hell. With a track like that no "uncompression" will save it. Which links into the argument if it is worth it to pay for lossless media. It always comes down to the original master and how the engineer treats the recording (and the equipment you listen through of course). Some artists excel at it. (Madonna, Sting, Nils Lofgren, Sara K, Chris Jones) and other plainly suck donkey balls. (Mostly rock-artists unfortunately but a distorted electric guitar is hard to get right)
