The programs involved are all freeware, and readily available. I will provide links for the non-controversial programs, but I will not provide a link, or tech support for the "questionable" one. My only suggestion is "google".
I suggest the following programs:1) fairuse4wm.exe
- this is the "questionable" program. It finds existing keys on your system and uses them to figure out and decrypt wma and wmv files, removing their DRM. (or something like that... it just works)NO LINK2) Jodix Free WMA to MP3 Converter
- easy to use, simple, but limited.LINK: http://www.wma-mp3.org/3) ID3-TagIT 3
- finish off by tagging your new MP3sLINK: http://www.id3-tagit.de/english/
