US Patent 7860830 Publishing, browsing and purchasing of groups of media items

Improved techniques to create, browse and/or purchase media asset groups are disclosed. Media assets groups can be created by various persons and published to a digital assets manager. Thereafter, the media assets groups can be finalized and made available for on-line purchase. Once the media asset groups are made available for on-line purchase, users can browse and/or purchase the media asset groups at an on-line media store. One example of a media asset group (group of media items) is known as a playlist, which can pertain to a group of audio tracks.
