Pruzhinki (Russian for "springs") is a compilation album of remixes by Russian deejay Muffin, a part of his t.A.T.u. + Rammstein project. The original CD was made in the European Union. The bonus tracks feature t.A.T.u. with Limp Bizkit and Zemfira with Rammstein and Clawfinger. In early 2005 a warez version of Pruzhinki was released. The album became more popular and was quickly spread by internet, resulting in numerous pirate editions and CD compilations. The album tracks appeared further at Last.fm, Youtube and Bit Torrent.
