Winamp and foobar can play encrypted WMA? I didn't think they could.
The only other method I knew of (and keep in mind, this was back in like 2006 before
FairUse4WM was created) was to burn the track to a CD, then re-rip it. But obviously with stuff like Zune Pass, you can't do that if the license doesn't allow it.
(I've only dealt in Wal-Mart music downloads back then, they were all 128kbps encrypted WMA. They then changed to mp3, like
Amazon did, and a few months ago just shut the store down alltogether since Amazon was beating them sales-wise)
SoundTaxi does (or at least DID, back in 2006) support WMA and unlike having to play it through the sound card and record the output, it somehow can directly convert it to other formats. So if you can't decrypt it, I'd say that's the next best option since conversion will sound better than recording, at least IMO.
Not quite sure if the program even works anymore, I'll try it myself and see LOL
--EDIT--
I have used
Tunebite too, that program *does* record through the sound card, in fact what it does is make a "fake" sound card that can play the audio back at 4x speed rather than real-time. It still basically records it though. How do I know SoundTaxi doesn't record it? It only takes like 15 seconds to convert a 4-minute song
