Singing games have them. The best is Singstar for the PS3. It has a whopping EIGHT Coldplay songs (The most of any artist in their catalogue!
). I have them all, lol, but suck at singing them. Singstar came with 'Clocks', and then I downloaded the other seven ('Shiver', 'Yellow', 'The Scientist', 'Speed Of Sound', 'Fix You', 'Talk' and 'The Hardest Part'). The online catalogue is constantly updated, so now I'm just waiting for the VIVA singles! The great thing about Singstar, is that it's the real artists and the real videos, so you can collect your favourite music videos on there, ha. Plus they are only $1.49 each, so it's just like ITunes, but you can not only have the video but particpate in it too...
Funny thing is, with all the songs I have sung on it (including non-Coldplay), 'The Hardest Part' is my highest score in the whole game, lol
It's a really fun group game though. Other than Coldplay, I particularly enjoy The Ting Tings tracks I downloaded
