Systems and methods are provided for aggregating a local media collection of a user with one or more shared media collections shared with the user to provide an aggregate media collection for the user. In general, one or more shared media collections shared with the user are first discovered. Optionally, the user may select one or more of the shared media collections for aggregation with the local media collection of the user. The shared media collections selected by the user, or alternatively all of the shared media collections, are then aggregated with the local media collection of the user to provide an aggregate media collection for the user. In one embodiment, bridging of users is provided to expand the sharing of media collections beyond those having direct relationships with the sharing user.
