shunnicutt writes "Apple has released iTunes 4.5 (and iPod software 2.2 and QuickTime 6.5.1) and relaxed some iTunes Music Store restrictions: now tracks you purchased can be authorized to play on up to five other computers, instead of three. However, they reduced the number of times you can burn a playlist to an audio CD from ten to seven. Another new feature is iMix, which allows you to publish playlists on iTMS, including comments on each track. The iTMS also offers a weekly free single for download."
adds "This release also changes their network sharing protocol in a way that breaks the open source iTunes sharing applications that have been released (based on my work on iTunes 4.2's DRM)."
kefoo writes "Among the new features is Apple Lossless Encoding, which claims to compress losslessly to half the size of uncompressed CD quality audio."
Hm, and I was about to re-rip all my CDs at 320 kbps MP3 ...

: I just tested, and I can listen to previously de-DRM'd AAC files from playfair, but I cannot use either playfair or FairTunes any longer. The former "Couldn't get DRM key for user," and the latter produces a blank file.
