Pascalini, as to the artists demanding and enforcing the way the medium is accessed, the problem is that the medium is now 1's and 0's, and the access point is almost anything electronic. After a sound (with sound being inherently analog) is converted to a digital form, it can be forwarded, copied, and pasted just like a line of text. All the information you see or hear from a computer is essentially the same stuff.
Look at it this way: you can build some little sand castles near the shoreline, and then build a nice big robust sand castle next to those ones, with a nice big sand wall and moat surrounding it. The little sand castles will wash away soonest, and the big one will take a little longer because it has all the extra stuff, but it will all wash away because it's all sand! That's what we're dealing with in the digital world as well. Everything is 1's and 0's, including the security and rights management software that protects the song which is also encoded in 1's and 0's.
With the information being freed from the medium, the only way to control the access of the music would be to control access to computers (or in my analogy above, the access to the beach.)
The point is this: Pandora's box has been opened. If you're familiar with that Greek myth you'll know that there was no way to get the evil back into the box, but there was hope contained in the box as well. The digital demon has escaped, but if the Labels could just recognize that this has also released an opportunity for amazing profits that can also make their consumers happy and their artists rich, then we would all be happier listeners!
