Most, but not yet all, iTunes Plus songs are now 99¢. Steve Jobs confirmed at the Wall Street Journal that the price drop was now in effect. I don't know yet if you can upgrade normal iTunes purchases to iTunes plus for free or whether you have to pay a slight fee to upgrade or if you have to re-purchase for the higher fidelity; free would be the bee's knees. I'm pleased to report that iTunes appears to be heading in a DRM-free direction. I think the arrival of Amazon's MP3 service is pushing the labels progressively forward. They can't give Amazon something and not give it to Apple; that would be a lot like the illegal collusion they've been accused of in the past.
