A website dedicated to bootleg music has compiled a three-CD box set dedicated to the phenomenon.
The collection features 432 unofficial remixes and bootlegs including samples of Kylie, Eminem and Craig David.
It is being sold under the names Boom_Selection_issue 01 and Nevermind The Bootlegs.
The three CDs can be played on MP3CD players, Macs or PCs rather than conventional CD players.
They are being sold via the Rough Trade record shop.
The Boom Selection website describes the release as "two fingers to the record industry."
