Researchers at Georgia Tech University have studied an office where workers shared music though Apple's iTunes software to find out whether the music you listen to changes the way co-workers think of you.

The employees questioned reported that they consciously worked to portray themselves in certain ways through their playlists. Some admitted to removing music from their playlists that they didn't think others would think was "cool".

The researchers found that users would try to find out which music collection belonged to which employee, but issues would arise when one person's interest in another's playlist was not reciprocated.

Georgia Tech associate professor of computing Beki Grinter told NBC: "We found that sharing your music is actually quite a strong personal statement."

The research found that music sharing served to build a community within the workplace.
