Benny - obviously in some ways you're right, and I guess I'm doing exactly what I moaned at other people for doing in the past, which is acting as if I have some kind of 'right of access' to the music, when clearly I don't.
But the only thing I would say is that it's not just amateur DJs as such that are shut out by this way of operating, it's any DJ that's not in close personal contact with the producers (and willing to get ripped off!). This is why I think the people involved are dreaming if they think they'll ever get widespread popularity or support.
Edit: if they're not interested in any of that, then fair play (but most that I've seen opinions from do seem to be, which is what is so weird/frustrating, it's like people can't put 2 & 2 together). But even then, what do you do if the DJ you've been selling dubs to gets sick of your sound or thinks they could get more money/bookings playing something else? You're screwed because you've got nowehere else to go to.
