A system generally includes a lock-screen capable application executing on a recipient computing device configured to facilitate user interface access to a communication function of the recipient computing device while the recipient computing device remains in a locked state. The lock-screen capable application is configured to intercept a communication received by the recipient computing device that is associated with at least one of a communication application or a communication service. The system includes a content association application executing on the recipient computing device to facilitate associating a media content item with the intercepted communication based on a relevance of the media content item with the intercepted communication determined from automatically processing the intercepted communication to identify an association based on metadata descriptive of media content items stored in a library of the media content items.
