There's lots of converters around. Google it. Seriously, google how to convert wma to mp3. For Real Player files I have a link but it's a commercial/shareware program:
http://www.rmconverter.com/ & I think Audio Hijack, from Rogue Amoeba
http://www.rogueamoeba.com/audiohijack/ & WireTap from Ambrosia Software

OK here's a search I did for FREE wma converters:

And I think MusicMatch might be your best bet for rm files. I think Winamp has a plugin for it.
Anyone else?
