I agree that most music out there is crap, but I'd just like to say that it costs a hell of a lot more than 25 cents to make a cd, when pressed in volumes the actual plastic disc itself probably costs 25c, but there's printing, cases, sleeves, inlays, then the things which aren't just material such as licensing, use of the actual equiptment to make the discs and cases, artist pay, workers pay, then there's promotion and plenty more costs..
I'm not saying that the price asked for most CD's is justifiable, but it does cost more than you think to make and promote these records.
