Why does clicking on any of the links on http://vkontaktecenter.ru/tools/vkontakte/audio/?search=queen result in a file download, but copy and pasting the link location (ie. http://vkontaktecenter.ru/tools/vkontakte/audio/get.php?f=http://cs4758.vkontakte.ru/u91234545/audio/3ec0dc2b6ce8.mp3&c=Queen%20-%20We%20Will%20Rock%20You)
results in a 404?
