I have to say that is a pretty compelling price point. A quick grep and du on some of my collection suggests that 1500MB is about 280 tracks at 192k.

The legal issues are interesting. I'd bet that it's legal in Russia, and that it's legal for us to subscribe to their club, thus leaving the RIAA in the sticky position of not wanting to draw attention to it. I notice on their quick guide page a note about observing copyright law pursuant to some license (number given). Obviously that could be bogus, but I doubt it.
