Truth, that line is too cynical. I dont think most people have an objection to paying for music so long as it's realistically priced & there's a visable pathway for the money to get back to the artist. If you want evidence, look at gig attendence which has risen dramatically over the last few years.
Myspace has emerged as a really good way for unsigned artists to develop a close, real-time relationship with thier fans - lots of artists I know use it for publicising gigs, and say it is a godsend for taking the guesswork out of booking venues, promotion etc. I think that maybe there's a tendency for electronic musicians to underappreciate myspace, because gigging isnt as central to what they do as it is in acoustic music. But if myspace add the ability to sell music onto the package and they can make it work, I think we might suddenly see a lightbulb going on above the heads of a lot of electronic musicians.
Re murdoch owning it - I'm not crazy about it either but I think it's the least worst option. I would love to have an international, cross-genre, not-for-profit collective of indie labels big enough to exploit the power of the net for the benefit of small artists on a scale comparable to myspace - like an early-years Rough Trade gone global. But we've had the net for a decade now, and nothing like that has happened. For whatever reasons, Myspace has emerged as the killer application and someone needed to come up with the funding to take it to the next level - if that's murdoch so be it. I dont think he's any worse than other media/technology conglomerate chiefs: i dont like his political meddling, but I think he's sincere in his vision for the future of media and I think he's bought myspace as a central part of that, not just as a cash cow. Maybe that's naive but we'll see.
These's loads of electronic musicians selling thier stuff on the web, but they're all doing it in isolation because there's no overall structure - Warpmart is the closest thing, but that's the tiniest of minnows compared to myspace. If this works it'll will be a massive shot in the arm for electronic music.
