Hey... While Hymn does not remove your AppleID it is still a good program, I would suggest it. I guess if youre worried about your friends sharing music on P2P, you shouldnt give your music to them man... I don't personally have a problem with you or I sharing music w/ friends, but just ask them to not put it on Kazaa or whatever.
Also, about the easiest way to find out if Hymn were using some SpyWare, is to look at the source code that you can actualy compile from. Ive looked at it, and its perfectly fine. As is DeDRMS and FairKeys.
If you would like something slightly more eye-friendly (hymn is a CLI) try this:
iRevolt an Apple DRM Scheme Removal App.
It uses the actual DeDRMS and FairKeys code written by Jon Lech Johannson (DVD Jon). If you would like, try it, if not thats cool too. (Note that this doesn't remove your AppleID either. :teufel8: )
Also, if you would rather learn how to remove the DRM encryption yourself (this way you can get rid of your AppleID if you would like) you can read a description of what the DRM is and how it is removed
here.
