Just in case you purchased a Sony CD “protected” by the rootkit DRM and want to claim your $7.50 worth of mp3s, SonySuit.com has all the available details on registering to take part. We’re still particularly interested in the precedent being set here by Sony: they have gone on record stating that $7.50 is the price of two full albums of digital music. And a few mp3s to have your computer’s security compromised still seems like a pretty crappy deal. But it’s better than nothing and every person taking part in the class action suit is helping send a message to companies trying to implement similarly sleazy DRM schemes. So go check it out, if you’ve still got that Celine Dion receipt in your wallet.
