receive, via the network interface from a computing device configured to control playback by a media playback device, data representing an instruction to add a playlist to a playback queue associated with the media playback device, wherein the playlist comprises a first audio track and a second audio track, and wherein the playback queue is maintained in data storage that is remote from the media playback device;

after receipt of the data representing the instruction, add the playlist to the playback queue, wherein after addition of the playlist to the playback queue, the playback queue comprises the first audio track and the second audio track arranged in a particular order within the playback queue;

cause the media playback device to play back the playback queue according to a continuous-playback mode;

while the media playback device is playing back the playback queue according to the continuous-playback mode via one or more speakers, repeatedly detect a continuous-playback trigger, wherein the program instructions that are executable by the at least one processor such that the cloud computing system is configured to detect the continuous-playback trigger comprise program instructions that are executable by the at least one processor such that the cloud computing system is configured to determine that a number of unplayed audio tracks within the playback queue is less than a predetermined threshold number of audio tracks, and wherein detection of the continuous-playback trigger is independent of user input; and

in response to detection of each continuous-playback trigger:
