Software copy protection?

As a copy protection measure, Sony BMG included the Extended Copy Protection (XCP) and MediaMax CD-3 software on music CDs. XCP was put on 52 albums and MediaMax was put on 50 albums. This software was automatically installed on desktop computers when customers tried to play the CDs. The software interferes with the normal way in which the Microsoft Windows operating system plays CDs, opens security holes that allow viruses to break in, and causes other problems. It is widely described as spyware.
