In various embodiments, an audio streaming service may provide a plurality of channels. On a particular channel, different types of content can be streamed to audio devices connected to that channel, including channel content, group content, and individual content. Channel content refers to same content that is streamed to all of the audio devices that are connected to the channel. Group channel refers to content that is selected for subgroups of the devices, and individual content refers to content that is selected for an individual device. Channel content may be transmitted to all the devices, then a period of group or individual content is provided, and then the devices are synced back into receiving the same channel content during a syncing window. Listeners can also interact with the content, such as skipping songs or adding songs to their personal collection.

A method for detecting the digital quality of a radio signal includes: receiving a radio signal including an analog modulated portion; digitally sampling an analog modulated portion of the radio signal to produce a plurality of samples; using a ratio between an average magnitude and an RMS magnitude of a block of the samples to compute an analog signal quality metric. Receivers that implement the method are also provided.
