How it works: When you play AAC file with iTunes 6.0, QTFairUse 6 dumps individual AAC files from the memory before AAC decoding (so you get better quality compared to direct sound recording software).
Unfortunately while removing DRM protection QTFairUse 6 doesn't save any metadata. The resulting AAC file, doesn't seem to play in iTunes. It plays fine in QuickTime Player, but iTunes on the Mac side rejects it.
