Mike Evangelist's Writer Block Live has an interesting post about his disdain for the Digital Rights Management (DRM) included in music purchased from the iTunes Music Store. In it he says that he's not going to "spend a another dime on content that I can’t use the way I please."
I'm pretty miffed about DRM as well, but also understand that Apple is a business and that they had to offer DRM as an olive branch to the record labels otherwise they'd never have agreed to be a part of the iTMS—and then where would we be?
In addition to Mike's rant on DRM, you really should read the 189+ comments which pretty much span the entire DRM argument from the me-toos to a self-proclaimed "famous music artist" who says "i hope someone comes into your house and rapes your family."
All this hatred over DRM? Get over it. If you really want to get around Apple's DRM before the new iTunes 6-compatible version of JHymn comes out it's not that hard to burn a CD and re-rip it. And there's always the quasi-legal AllofMP3.com for the people that want to pay something, just not 99 cents per song.
At the end of the day, it's on your conscience. You know full well when you're stealing music. If you want to continue to enjoy music from your favorite artists in the future you need to support them, not steal from them.
