The method of claim 1, wherein the method further comprises: for each frame of the plurality of frames, generating the time stamp for the frame, wherein the time stamp for the frame indicates a time that is later than a current time of the device clock of the first playback device by a first duration of time. 5. The method of claim 4, wherein the first duration of time is based on a time required to transmit a single packet from the first playback device to the second playback device. 6. The method of claim 5 further comprising: receiving a message from the second playback device indicating that the second playback device needs additional time to process frames received from the first playback device; andin response to receiving the message, increasing the first duration of time used to generate time stamps for frames that the first playback device generates after receiving the message. 7. The method of claim 6, wherein the first playback device and the second playback device remain independently clocked while the first playback device plays the audio content in synchrony with at least the second playback device. 8. The method of claim 1, wherein an individual frame further comprises a frame sequence number indicating the individual frame's order in the plurality of frames. 9. The method of claim 1, wherein the portion of the audio content in an individual frame comprises a set of one or more audio samples. 10. Tangible, non-transitory computer-readable media comprising instructions encoded thereon, wherein the instructions, when executed by one or more processors, cause a first playback device to perform a method comprising: receiving audio content via an asynchronous network;generating a plurality of frames, wherein an individual frame is generated at a given time, and the individual frame comprises a portion of the audio content and a time stamp indicating a time after the given time to play the portion of the audio content;generating a sequence of packets, wherein an individual packet comprises one or more of the generated frames and a packet sequence number indicating the individual packet's order in the sequence of packets;transmitting the sequence of packets comprising the plurality of frames to at least a second playback device via the asynchronous network;transmitting device clock timing information representing a time value indicated by a clock of the first playback device to at least the second playback device via the asynchronous network; andplaying the audio content in synchrony with at least the second playback device by using the time stamps and the device clock timing of the first playback device. 11. The tangible, non-transitory computer-readable media of claim 10, wherein transmitting the sequence of packets comprising the plurality of frames to at least the second playback device comprises transmitting the sequence of packets via a multicast network address. 12. The tangible, non-transitory computer-readable media of claim 10, wherein transmitting device clock timing of the first playback device to at least the second playback device comprises transmitting the device clock timing via a unicast network address. 13. The tangible, non-transitory computer-readable media of claim 10, wherein the method further comprises: for each frame of the plurality of frames, generating the time stamp for the frame, wherein the time stamp for the frame indicates a time that is later than a current time of the device clock of the first playback device by a first duration of time. 14. The tangible, non-transitory computer-readable media of claim 13, wherein the first duration of time is based on a time required to transmit a single packet from the first playback device to the second playback device. 15. The tangible, non-transitory computer-readable media of claim 14, wherein the method further comprises: receiving a message from the second playback device indicating that the second playback device needs additional time to process frames received from the first playback device; andin response to receiving the message, increasing the first duration of time used to generate time stamps for frames that the first playback device generates after receiving the message. 16. The tangible, non-transitory computer-readable media of claim 15, wherein the first playback device and the second playback device remain independently clocked while the first playback device plays the audio content in synchrony with at least the second playback device. 17. The tangible, non-transitory computer-readable media of claim 10, wherein an individual frame further comprises a frame sequence number indicating the individual frame's order in the plurality of frames. 18. The tangible, non-transitory computer-readable media of claim 10, wherein the portion of the audio content in an individual frame comprises a set of one or more audio samples. 19. A first playback device comprising: one or more processors; andtangible, non-transitory computer-readable media comprising instructions encoded thereon, wherein the instructions, when executed by one or more processors, cause the first playback device to perform a method comprising:receiving audio content via an asynchronous network;generating a plurality of frames, wherein an individual frame is generated at a given time, and the individual frame comprises a portion of the audio content and a time stamp indicating a time after the given time to play the portion of the audio content;generating a sequence of packets, wherein an individual packet comprises one or more of the generated frames and a packet sequence number indicating the individual packet's order in the sequence of packets;transmitting the sequence of packets comprising the plurality of frames to at least a second playback device via the asynchronous network;transmitting device clock timing information representing a time value indicated by a clock of the first playback device to at least the second playback device via the asynchronous network; andplaying the audio content in synchrony with at least the second playback device by using the time stamps and the device clock timing of the first playback device. 20.
