(CNN) -- Your friends don't need to know about every song you hear on the radio. That's the position Pandora has taken toward a new Facebook feature that lets users automatically publish information to their profiles about songs they listen to, videos they watch and articles they read. Pandora, which makes the popular personalized Internet radio service, isn't just concerned about clutter in your Facebook friends' news feeds. Some listeners could feel violated when they learn that an application is broadcasting information about their activities, Pandora executives said. "It's true that music is a social experience, but it's also a very private experience," Pandora founder Tim Westergren said in a recent phone interview. "We have to be very cautious."
