harigeharry I'm one of those stupid addicts that will pay to see the best (in this hypothetical case, high bitrate 16k files) regardless provided it's not priced like gold. But hopefully there's not enough people like me to go around and support a per-file-charge-system.
My guess would be they charge big to start as most everyone buying 16k files are the 9 AVP users on here, lol. Then it comes down in pricing model overtime.
Or they could be kind and just post the file, considering it an infrastructure investment pulling in customers slowly overtime.
