Abstract: Systems, methods, and computer program products are provided for managing a playlist on a portable media device including generating a random order of media items based on a seed, receiving an instruction to power down the portable media device, saving the seed in a storage, and powering down the portable media device.

Abstract: Systems, methods, and machine-readable media are disclosed for controlling an electronic device using data transmitted over radio signals. In some embodiments, a radio source may embed instructions to control an electronic device into a radio signal. For example, the radio source may use the RDS communications protocol to transmit the instructions in an FM radio signal. The electronic device may receive the radio signal and may perform the instructions included in the radio signal. For example, in a testing environment, the instructions can include commands to test the electronic device's radio using test parameters specified in the instructions. Responsive to receiving the test parameters, the electronic device may configure itself (e.g., turn on or off certain components) and record audio from a specified radio station.

Abstract: Methods, systems, devices, and apparatus, including computer program products, for memory management. Usage data associated with one or more files is identified and stored in a volatile memory of a device. The usage data is maintained in the volatile memory is maintained during and after a reset of the device. After the reset, the usage data can be written to a non-volatile memory.
