This shouldn't affect songs you've already ripped.rendezvouscp said:I hope that it doesn't include AAC files that are already encoded, but rather encodes them how you want while attaching DRM to the result file.
What they're doing is releasing a multi-session CD, with a copy-protected audio session and a data session containing DRM'ed tracks.
Windows systems, due to their peculiar design, can only access the last session of a CD, so they see these as data discs and not as audio CDs. Using proper software, you can get around this Windows restriction and access the audio session (which is what plays when you put the disc in an audio player.) If you have a ripper that uses error correction, it will rip just fine, even without DRM.
On Macs, it's even simpler. These dual-session discs show up in the Finder with two disk icons. One for the audio session and one for the data session. The point of this news article is that they're going to put FirPlay-DRM files in the data session in addition to whatever they're providing now (probably WMA). But it should still be no big deal to rip from the audio session using iTunes, although you may have to turn on error correction to do it.
Discussions about the bit-rate of the bundled data files are irrelevant unless they manage to make a disc that iTunes can't rip. But I would be very surprised if they could make such a disc without making it unplayable on the majority of audio CD players.
