Leo en tomatoma.ws que el grupo Chumbawamba ha pedido a su discográfica no proteger el disco con ningún sistema anti-copia. La explicación (que recomiendo leer en su página web el artículo completo) se resume en esto:

History has a habit of repeating itself – consider some earlier examples of the Music Business getting hot under the collar:

Early US records (eg Brunswick Records, who released, among others, Robert Johnson) had “Not for play on Radio” stamped on them, for fear that radio play might harm Sheet Music sales.
Later, in the 1970′s, the Record Business claimed “Home taping is killing music”. Don’t make me laugh – home taping was a fantastic, free way of promoting records, just as Radio play (and P2P file-sharing) is.

With all this in mind, we asked our label not to use any copy-protection on our latest CD, despite their normal policy. So, despite the warning on the sleeve, “A Singsong and a Scrap” is not copy-protected. I have successfully played it in both Mac and PC (Windows 98 and XP). If anyone finds otherwise, we would like to know.

Commercial Piracy is one thing (and copy-protection won’t stop it), but buying a CD only to find it won’t play on your PC is just such a piss-off, it’s enough to drive you to P2P downloading.

Joder, más claro, agua. Sacad vuestras propias conclusiones.
