I know I'm in the minority but I think people should PAY the people who are trying to make a living from recording music, I don't care at all if the cost of a CD is too expensive for a "poor" person to buy, if you can't afford it you can't have it, just like anything else in life.
The thing is you can, therefore the logic is flawed... and by theft you ought to take something out of someone, exactly what are you taking and from whom? If you don't get money trough exploration, you find another way to do it, not blame others for not going into the mood...
Addendum: Roj has explained it very well
