I know there are so many downloading software which have DRM tech like Napster, Rhapsody, limewire, iTunes, bearshare.......
So I don't like DRM at all, it's so frustrating when can't do what you want with the music you bought from internet,like transfer and share it with my friends or convert it to other formats which can be played by other devices. And it's not easy to find a good converter to help me with those problem.
