The (re)birth of a properly open artist centric social music platform?

So apparently muxtape has been reborn as  a sort of attempt to do MySpace Music correctly.  It seems to early to tell if this will work out for them, but I'm really  hoping that 'correctly' means a gratuitously open api and quality linking open data compatible rdf.  Though really none of that will matter if they don't get past the critical mass threshold of users/participants.  We'll classify this one as wait and see...
