I registered here just to point out that you have no idea what your talking about. Coldplay (of which I'm not a huge fan of) has turned down multi-million dollar deals from large companies to use their music in ads.
If it was just about the money, why would they do that? Not to mention, they are, by the sheer nature of their music, not interested in "selling out" or they would be much more pop then they are.
I just hate to see people say things out of ignorance and assume that everyone that has money is only interested in it. They earned what they have through the blood and sweat of their music and their performances. Don't belittle that with retarded comments like the ones you made.
