The program works well for what it does, and is fairly well implemented. It is not without problems, however.

If you use this to remove DRM from an audio file, and save as anything but .AIFF, .WAV or Apple lossless, you will lose quality. If you do use those formats the new files will be a LOT bigger. The reason for this is simple - you are expanding, then re-compressing, the file. You will be adding compression to a previously compressed file, plain and simple, which means even much more loss. Whether you find the result acceptable depends on a lot of things: original file quality, type of audio (vocal, music etc.), and your own personal tolerance for lowered fidelity.

It also will only work on files that you can use on your computer, and will not help if you have a DRM locked file from another person.

SInce JHymn (http://hymn-project.org/jhymndoc/) broke starting at iTunes 6.0, and apparently is going to stay broken for the present, this is the only way to do it unless you pay more for non-DRM files at the iTunes store (and if they are even available for the particular audio you want). JHymn was a REAL DRM remover, not a re-compressor.

That being said, this kind of thing does work, and is a lot easier than burning a CD and then importing the resultant files. It may good be enough for you, and is all there really is right now.
