They aren't at all Jason did have an account and I think Tom did but they had to used up there account fast because they said that they didn't by song on a monthly basis at all.
It seems like CNET and almost all of the major IT publications (except Ars) completely ignore eMusic; and I don't think that's fair.
These are 190-320 DRM Free MP3's encoded in VBR; they have apps for Windows, Mac and Linux, and it's brain dead easy to download from the browser. The songs are much cheaper, about 24 cents a track. And you won't find Britney Spears in their catalog, just quality indie music.
I say you give eMusic a chance. And I have some invites, leave a message if you want one.
