Ok, so you can burn these to CD right? You can rip them right off too, right?
Yes and yes.
If you burn a DRM-protected WMA file to disc (into the likely CDA format), you'll be okay.

That's the easy way to get around the DRM.
(That's how I gotten around any DRM-protected tracks I've gotten from like Best Buy, who have offered for buying CD's free DRM-protected tracks to download for buying a certain CD, in the past).
Then, if you want afterwards, you can convert that disc copy (which is likely to be CDA format) to whatever file type you want onto hard drive if you want (MP3, OGG, WAV, etc etc) and not sweat any DRM..
You might have to do a hell of a lot of burning, if you bought a lot from WalMart's Music Store, though...that would suck. And even suckier would be if you want to rip 'em back to your HD, too.
With Walmart making this move there's hope for all this DRM crap to crumble and fall.
That's the good thing -- that WalMart got rid of DRM for their music, back in Feb. 2008.
