Hi
I used this cool prog drm-removal and used it for removing drm from itunes protected audios a years ago, it did the job well, btw. Then I bought mp3 player and it could't play my wma files so I decided to عفوا ,,, لايمكنك مشاهده الروابط لانك غير مسجل لدينا [ للتسجيل اضغط هنا ] with drm-removal. It works like a charm! Just in a few clicks, you only need to click "Add" button and choose the folder of wma files. They will convert all the files at once at a really high speed. If you have the same question and need to convert wma to mp3, you should try drm-removal!
I am big addict :) of audiobooks and actually wonder, if it legal. I bought a book (now its mine!) from napster, but may be its drm and I can't copy it to my MP3 player!! Thats dick!! I can remove drm - but what about legacy?

thanks in advance!
