It looks like that nowadays the music industry focus more and more on their profit and lost the focus on the customer. In the end, this could result in situations where I could be fined for making a copy of a CD with DRM that I officially bought. With DRM applied I have in principle no permission to make a copy of the CD to play it e.g. in my car. So for me it was time to search for alternatives without such kind of legal restrictions.
I found a license which is comparable to the General Public License but for creative commons, the Creative Commons License. For example music under this license is free to copy and distribute, a great development (like the GPL stuff). If you want to listen to music licensed by this type of license (and you like electronic music), visit http://www.mixotic.net/.
