5. The system of claim 1 , wherein the client device displays an audio playback graphical user interface including a scrub bar to control audio playback by the user, and wherein a rewind command from the user is received by the client device at the scrub bar of the audio playback graphical user interface to cause the client device to toggle from outputting the live digital audio stream to outputting the time-shifted digital audio stream.
6. The system of claim 1 , wherein the media content server, time-shifted media server and alternative content server are integrated into a single server.
7. A system, comprising:
a client device comprising:
a processor
a display and
a speaker,
the processor configured to:
receive a live digital audio stream from one or more remote servers and output the live digital audio stream via the speaker of the client device,
in response to a playback command by a user at an audio playback graphical user interface on the display, request and output a time-shifted digital audio stream received from the one or more remote servers; and
while outputting the time-shifted digital audio stream:
receive a respective alternative content (AC) start/stop tag of a plurality of AC start/stop tags of the live digital audio stream from the one or more remote servers as the one or more remote servers identifies the respective AC start/stop tag from the live digital audio stream,
identify an upcoming alternative content period indicating when a first alternative content was inserted in the live digital audio stream based on the respective AC start tag and a respective AC stop tag, and,
in response to determining that the upcoming alternative content period is within a pre-determined timing threshold, transmit an alternative content request to the one or more remote servers;
receive a second alternative content, and
when an upcoming alternative content period matches a current period of the time-shifted digital audio stream:
cease outputting, at the speaker, the time-shifted digital audio stream, and
