The user-specified location preference indicates that a user has selected between receiving perishable content associated with a specified static location and perishable content associated with a current user location. a processing device included in a media delivery platform, obtains perishable content items selected in accordance with the user-specified location preference, assembles the perishable content items into an add-in block, and delivers the add-in block to the streaming media service. The streaming media service inserts the add-in block into a media stream associated with the user, and delivers the media stream to a user device.
