I would like to pipe in if I may.
I only purchase my online music from MP3tunes.com. The reason? Not only is it legitimate and inexpensive, but they document how much goes to the artists. I used to buy from iTunes alot, but I do not like the DRM restrictions. If I buy the song for my personal use, I should be allowed to have the song on every computer in my house, my iPOD, a cd player for the car, and my entertainment server. iTunes restricts what I can do with something I have purchased. Within reason, I feel it is okay to do that.
There are artists that do offer their music for free on the web and that is legit. They are the owners of the property and can distribute is as they with. When you download free music that is not approved by the owner...you are stealing, case closed, end of story. Legally, you are stealing, morally you are stealing. You may call the RIAA Machiavellian crooks and you may be right to do so. If I steal from the old lady down the street from me, I am a thief. If I steal from a crime bosses home, I am a thief. Either way, I have taken something that is not mine. The moral position of the person I stole from does not change my act.
Now, DRM is beginning to bug me. Under the fair use provisions on the DMCA, you are allowed to make a backup copy of your media. That includes back up cd's, dvd's etc. Sony recently put measures to prevent you from copying their cd's that inadvertently harmed computers running the Windows Operating system. It installed a rootkit that you could not remove easily until they released a patch...after denying they did anything wrong.
Anyway, other measures that they do is to copy protect the cd's in such a way that the fault tolerance on the CD is reduces. This produces a cd with s shorter life span. So you are now better off breaking the DRM and copying it so you have a copy with acceptable fault tolerances. That action is defensible due to fair use.
At the end of the day it is kind of like having a car. You can drive places with it and use it as a utility. You could also murder and commit crimes with a car. The device is not more or immoral. The person behind the wheel is. We have choices when we go online and listen to music. We can make the right choices or the wrong choices, but it is not up to sony to restrict my ability to use the technology in a correct manner just in case I decide to use it in an incorrect manner.
