I don't like the interface. It is messy. But that is my opinion. It is also a bit on the slow side on un'DRMing my music.
I really don't want to aggregate to facebook either and I think this is where they want to place this product.
But it is a beta, and so far it seems to be doing what it said it would do. So I can't really complain because it is free as well.
I'm trying it right now and although the UI is pretty weird, it seems to be doing what it was supposed to. The only thing I need is someone to add as a friend to share a couple of (now)Un-DRM'ed songs and see if this works too.
