METHODS AND SYSTEMS FOR ADAPTING PLAYLISTS

A method is performed at a server system. The method includes, while streaming a playlist at a first electronic device associated with a host listener, the playlist including media content items: automatically receiving an identity of a guest listener having a second electronic device, without explicit input from the guest listener after the second electronic device comes within range of the first electronic device; selecting an additional media content item based at least in part on the identity of the guest listener; and incorporating the additional media content item into the selected playlist.
