Abstract: Systems and methods associated with selectively initiating a social interaction based on affinity between personal electronic devices are described. One example system includes a data store to store playable content and a content organization logic to create a playlist of playable content. The system may include a communication circuit to communicate with a remote PED. The circuit may acquire information describing a playlist in a remote PED. The system may include a social agent logic to determine a degree of affinity between the PED and the remote PED. The degree of affinity may be based, at least in part, on a comparison of the playlist associated with the PED and a playlist associated with the remote PED.
