Music file DRM

Anybody know how to convert a protected .wma file?  My sister bought a track in this format and needs to put it on her ipod.

I don't buy music online, so I haven't been keeping abreast of how this stuff is done.

I've read an article about this recently but I don't remember which issue and I can't be arsed to search through my mags. There is a method however.

If you can't find it and all else fails, you can always copy it the old fashioned way, with a good analog cable.
