Methods, systems, and media for providing dynamic media sessions with audio stream expansion features

A system for media playback, the system comprising:

• a leader device;
• a plurality of candidate follower devices, wherein the system is configured to:
• create a group of devices that are explicitly grouped together by a user;
• cause media content comprising video content and audio content to be presented by the leader device;
• receive a voice command to alter presentation of the media content, wherein the voice command indicates the group of devices explicitly grouped together by the user;
• identify a plurality of devices connected to a local area network with which the leader device is connected from the group of devices;
• identify the plurality of candidate follower devices and a non-candidate follower device from the plurality of devices connected with the local area network, wherein:
• each of the plurality of candidate follower devices and the non-candidate follower device have a respective characteristic, and the characteristic of the plurality of candidate follower devices is different than the characteristic of the non-candidate follower device,
• the characteristic is indicative of whether the corresponding device has a display screen;
• and
• transmit, to the plurality of candidate follower devices, a control instruction that causes the audio content of the media content to be presented synchronously by the group of devices with the media content presented by the leader device.

• cause a user interface to be presented that presents the plurality of candidate follower devices;
• cause a selection button to be presented in association with each of the plurality of candidate follower devices but not in association with the non-candidate follower device;
• and
• transmit, to the plurality of candidate follower devices, a control instruction that causes the audio content of the media content to be presented synchronously by the group of devices with the media content presented by the leader device.
