It`s a legitimate way to get music online, with funds going to who they `should`. The amounts/quantities they can argue between themselves and thrash it out.
But - the worse case scenario for the music people would be for iTunes to drop the drm sales completely, and make the likes of iTunes(or a new variant) that just plays regular music.
Sounds good, but people will get their music - by any means necessary. Currently they have a source of income for their tunes, without iTunes completely, people will increasingly discover u don`t need to pay anything.
DRM is eventually going to bite itself on the arse. Perhaps it`s had it`s glory and time to pack things up completely.
Makes no difference to me what they do.
