One of the many things people do online is sharing what they are listening to, with friends on Facebook. If you're a regular Facebook user, chances you have at least one friend who constantly shares what he or she is listening to. Sometimes, it can be annoying, but it's about to get even more so.

Pandora, one of the largest music listening services on the Web, has gotten an overhaul that makes it much easier for listeners to share content with their Facebook friends. This feature does not only work on the Website, but also with the Android and iOS apps.

The thing about the new Pandora, is that once you command it to publish your music listening habit to Facebook, it will automatically do so until you see it fit to break the command. Millions of Facebook users around the world are now in for a flood of music recommendations on their timeline, which means many Facebook users, could end up being blocked by their peers.

"Music is a central part of many people's lives and at Pandora we recognize that it can be both an intensely personal experience and a highly social experience," Pandora Chief Technology Officer Tom Conrad said in a statement to CNET. "For those who want to share, Pandora's new timeline app serves as another platform for music exposure and discovery, which benefits listeners, artists, and advertisers. With Facebook's recent addition of the Music section for timeline, we're now offering personalized social sharing experiences for every type of listener."

If you're a Pandora user and you don't want to use this feature, it is very easy to opt out and keep your music tastes private. Then again, if many of your Facebook friends also use Pandora, this music sharing feature could allow for finding new songs to listen.
