Anyway. You do have to use iTunes, (unfortunately if you're on a PC, since it kind of bites, from what I know) since iTunes is essentially a portal to the iTunes Store. Also, it's only available on AAC, so you're probably out of luck with that one. I think a lot of the quality problems are perception issues; I don't know that people who have listened to it do hear the issues. I'm not sure.
In any case, for DRM to work with her player, her player has to support that particular flavor. Most likely, her player supports Microsoft's Plays4Sure (unless it's fairly old or a Zune), so she should use one of those stores, which include Napster, Rhapsody (which is Real media--I'm pretty sure they're P4S now), um... and some other ones I don't remember the names of.
