The QTFairUse 6 application supports iTunes versions 6.0.4 to 6.0.5 and uses Apple's music and video player in the DRM-removing process.
QTFairUse 6 is available for Windows only. It requires Python 2.4 and runs in the command line.
You may download QTFairUse 6 from the following URL

How it works: When you play AAC file with iTunes 6.0, QTFairUse 6 dumps indiividual 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.
Alternatives:
1.
Remove DRM from iTunes 6+ with SoundTaxi.
SoundTaxi works with iTunes 6+. Although it re-encodes your files, but it can keep the artist, song title, year and album metadata.
2.
Use iTunes 5 and less with JHymn
