Various embodiments enable a user of a mobile media device to select one or more channels to load onto the device. Each channel comprises a collection of media content files, such as video content, audio content, and so on. Each collection of media content files can be associated with a particular genre (or genres) of media content. A channel can be managed such that its collection of media content can be rearranged, augmented, and/or otherwise edited to produce a refreshed version of the channel. The refreshed version of the channel can be provided to the mobile media device for playback. Thus, a channel associated with a particular genre of media content can provide a user with a dynamic user experience without requiring the user to manipulate specific media content files.
