If the wma songs are protected by licencing then to my knowledge there's not much that can be done. But as far as converting wma to other formats there's plenty of utilities that can do that depending whether you use mac/windows/linux. Do a google search for 'wma conversion'. Else I can suggest a few. Better still don't downld wma or wmv files. Go for mp3, etc. or mpeg/mpg/avi/divx/3ivx/etc.
