Remote Creation of a Playback Queue for an Event

Example embodiments involve remote creation of a playback queue for an event. An example implementation involves a computing device receiving, via a control interface, input data representing a request to create a playlist for an event at a particular future time and date and a designation of multiple invitees to the event and sending, via a network interface to a cloud computing system, instructions representing the request. The instructions cause the cloud server(s) to send, to multiple second mobile devices corresponding to the multiple invitees, one or more respective invitations to the event. Each invitation indicates: (i) a future time and date for the event and (ii) a link to a web interface including user interface controls to add audio tracks to the playlist for the event. During the event, the computing device causes the playlist to be queued in a queue of a media playback system for playback.
