"The Texas attorney general said on Wednesday that he added a new claim to a lawsuit charging Sony BMG Music Entertainment with violating the state's laws on deceptive trade practices by hiding "spyware" on its CDs.
Attorney General Greg Abbott filed the original lawsuit in November, accusing the company of violating state anti-spyware laws by embedding software in its CDs and media player to monitor users' habits.
The new charges brought by Abbott contend that MediaMax software used by Sony BMG to thwart illegal copying of music on CDs violated state laws because it was downloaded even if users rejected a licence agreement.
Abbott said in a statement: "We keep discovering additional methods Sony used to deceive Texas consumers who thought they were simply buying music."
The original lawsuit contends that Sony BMG secretly installed copy-protection software, using XCP programs, that was extremely difficult to remove from users' computers.
Sony said it has recalled the CDs, which feature music from 52 popular artists including Ray Charles, Frank Sinatra, Louis Armstrong and Celine Dion.
Critics have said the MediaMax software lets the company track customers' listening habits even if customers reject maker SunnComm's terms in a licensing agreement that appears upon installation."
