Abstract

Methods and systems that facilitate the downloading of media items to a first network device from a second network device are disclosed. A plurality of media items are identified. Media item metadata associated with the plurality of media items is obtained from the second network device and stored on the first network device. Media item content data associated with a first subset of the plurality of media items is obtained from the second network device and stored on the first network device. In this manner, only media item metadata associated with a second subset of the plurality of media items is stored on the first network device.

wherein the content update policy for the song type specifies obtaining and storing media items based on a release date.

7. The method as recited in claim 1, further comprising:

determining by the first network device whether sufficient memory is available in the first network device to store additional media item content data based on the content update policy; and

executing the obtaining and storing of the additional media item content data by the first network device only when sufficient memory is available.

8. The method as recited in claim 1, further comprising:

determining by the first network device whether the additional media item content data for at least one media item in the media library can be retrieved from the second network device;

when the second network device is not available, delaying by the first network device the obtaining and storing of the first media content data by the first network device until the second network device is available.

9. The method as recited in claim 1, further comprising:

receiving by the first network device notification from the second network device when one or more changed media items have been added;

obtaining from the second network device and storing on the first network device media item metadata for at least one of the one or more of the changed media items that have been added.

10. The method as recited in claim 1, wherein the additional media item content data obtained and stored in response to the playing of the first media item content data is limited to a subset of media items in the plurality of media items based on one or more user-established settings.

11. The method as recited in claim 1, wherein the additional media item content data obtained and stored in response to the playing of the first media item content data is limited to a subset of media items in the plurality of media items based on a history of use by a user of the first network device.

12. The method as recited in claim 1, wherein the media type is selected from among a group of media item types consisting of:

podcast media, movie media, television media, and music media.

13. A portable electronic device configured for downloading media items from a network device, the portable electronic device capable of playing at least one type of media items available in a media item library accessible by the network device, comprising:
