Brilliant and convenient but you're still paying for pirated music. There is no difference than if had you downloaded if from a newsserver or via torrent - for free. Just because you're buying it doesnt make it legal.
Its very different from trawling a newserver or torrent site.

Your claims of piracy are unfounded.
The site claims to operate under current legitimate Russian law, and under license.
The claims being made by the representatives of the license holders are being tested in court, but not yet proved. (And seem to be based on them changing their mind about having granted the license in retrospect.)
If at some time in the future the law changes, it still means that right now its legal.
If you dont want to give it to your friend then thats just silly. He's not gaining any security or piece of mind by buying it either.
No giving it to my friend would be piracy.

As you should well know.
My comment was about how online music stores *should* be - prices so low that your friend would be ashamed to ask you to copy music that he could easily afford himself.
