This isn't exactly piracy, because it's allegedly legal in Russia, but I can guarantee you they're doing it without the consent of the record labels or the artists. So really, you are still stealing form the copyright owners, or more exactly, the people who own that website are stealing from the copyright owners.
So technically, it is piracy. I'm no fan of the big 5 record labels (down to 4, now after yet another mega-merger) but there's just no way to see this as a good thing for music, in general.
Support your local, independent artist, by giving them the price they need to make a living.
