All these stupid anti-piracy gimmicks are really messing up the way people view the entertainment industry. I think it is personally resonable for a person to buy a CD, be able to play it on any audio system they want and also make as many copies of the frickin' thing as you want also. I have multiple of copies of all my CD's mainly because I keep a set at my house, a set in my car, and usually a set in a travel CD case if I am going to be studying somewhere for a long time or what not.
Also, it has been proven that when people download music and they like what they hear; they will go out and buy the CD. Personally, I think that if you buy a CD without ever listening to it and you end up not liking it at all then you should be able to get a refund (as long as the CD is in perfect condition upon return). I have not trusted Sony for years because they appeal to the main stream (which is briliiant marketing and that is why they are such a powerhouse). I prefer to look at companies that dare to do something different and also make quality products that you do not have to worry about.
