Abstract: An arrangement (100) and a method are disclosed for sharing a content item (101), such as a music title, with a second user. A first user (110) grabs a piece of music from the title and sends said piece of music to a friend (130). The user device (110) adds a content identifier and a user identifier identifying the sender to the transmitted piece of music. The recipient reproduces the piece of music (102). If he or she subsequently decides to buy the complete title, the sender will obtain an award from the content owner (130) for promoting the title. This electronic version of “mouth-to-mouth” marketing encourages people to spread music clips and may persuade friends to purchase content items.
