A non-transitory computer readable storage medium for a first portable media player, the computer readable medium comprising:

• a first instruction code for playing back a first media file on the first portable media player;
• a second instruction code for accepting user input from a first user into the first portable media player during playback of the first media file;
• a third instruction code for generating a first control signal based on the user input for influencing operation of a second portable media player;
• and
• a fourth instruction code for transmitting the first control signal from the first portable media player to the second portable media player, wherein the playback of the first media file instructs the first user of the first portable media player to perform a first activity of a group activity, wherein the first control signal is configured to influence playback of a second media file by the second portable media player, and wherein the playback of the second media file by the second portable media player instructs a second user of the second portable media player to perform a second activity of the group activity.

A master electronic device for coordinating a group activity, the master electronic device comprising:

• a master communication module configured to communicate with a first member communication module disposed in a first member electronic device and with a second member communication module disposed in a second member electronic device;
• and
• a controller configured to:
• generate a synchronization signal for synchronizing playback of a first activity file by the first member electronic device and playback of a second activity file by the second member electronic device;
• and
• transmit the synchronization signal to each of the first and second member electronic devices via the master communication module, wherein:
• the playback of the first activity file instructs a first user of the first member electronic device to perform a first activity of the group activity;
• and
• the playback of the second activity file instructs a second user of the second member electronic device to perform a second activity of the group activity, wherein the controller is further configured to:
• accept first input data generated by the first user during the playback of the first activity file by the first member electronic device;
• accept second input data generated by the second user during the playback of the second activity file by the second member electronic device;
• and
• generate a first control signal for influencing the operation of the first member electronic device based on the second input data, wherein the second input data comprises speech of the second user during the playback of the second activity file.
