First my personal prejudices: I love Apple's Music Store. I don't mind the DRM because it does allow me to burn a few audio CDRs to back up the music. I am getting really annoyed with people trying to circumvent iTunes DRM.
People who produce content own it. Period. I earn my living by authoring published books and writing proprietary software for customers. I also enjoy writing free web books and releasing major projects like KBtextmaster as open source. My choice in what to do with stuff that I create.
I don't like the music industry because they tend to screw over musicians, but the world is not a perfect place. Steve Jobs did a great job negotiating with the music industry to set up Apple's Music Store. I enjoy it and I am willing to follow the terms and conditions of use. People who don't like it should not try to spoil it for other people.
BTW, I am a huge fan of Lawrence Lessig (I was once the featured commoner on the Creative Commons web site, which was fun). He strikes such a reasonable balance in copyright issues. The free mix CD in Wired magazine was cool and fun.
