Just to make a point about mp3fiesta as bonj mentioned it, using this Ukrainian site (and there are quite a few similar ones) is seen by copyright authorities as equivalent to piracy.
Such sites are legal under Russian/Ukrainian law, but they (claim to) pay a tiny royalty percentage to a local organisation that the copyright holders will not deal with. So, the net effect is one of obtaining an MP3 where the copyright holder has not been paid royalties, no different from grabbing the MP3s via BitTorrent. There have also been claims that these sites have been linked with organised crime, which may or may not be true.
In essence, if you are happy using MP3Fiesta (or similar) then you might as well save yourself a few quid and download using a P2P service!
