1. A media-reproduction device for adaptively reproducing media objects based upon social context within proximity to the media-reproduction device comprising: an output device for reproducing a media object; and a control circuit configured to: identify a person in proximity to the media-reproduction device; identify at least one additional person in proximity to the media-reproduction device; determine a social context based upon an analysis of social data corresponding to the identified person, social data corresponding to each of the at least one additional identified persons, and a surrounding environment in proximity to the media-reproduction device, wherein: the social data is received from a social and/or professional networking website; the social data identifies a relationship between the identified person and each of the at least one additional identified persons, the relationship specifying at least an existence of a preexisting relationship or a lack of a preexisting relationship; and the social context is determined based on the identified relationship between the identified person and each of the at least one additional identified persons, such that: if the identified relationship specifies the existence of a preexisting relationship between the identified person and each of the at least one additional identified persons, then at least one media object is selected for reproduction on the output device from an account at the social and/or professional networking website of the identified person or one of the at least one additional identified persons; if the identified relationship specifies the lack of a preexisting relationship between the identified person and at least one of the additional identified persons, then at least one media object is selected for reproduction on the output device that is not from the account at the social and/or professional networking website of the identified person or any of the at least one additional identified persons; reproduce the at least one media object on the output device, and the media-reproduction device comprising a mobile phone having a display, the output device comprising the display of the mobile phone, and the control circuit is configured to identify at least one additional person in proximity to the media-reproduction device via information received from a mobile phone of the at least one additional person.
