avifile decodes WM8 and higher movies.   I assume that means wma as well.  
Although I'm not sure how it handles files without video.  I'm sure the code 
can be altered to play just the audio though if that's the case.   

You're probably going to see record labels advertising True cds to try and 
get more sales than those advertising the retarded broken cds with wma crap 
on them.
