Systems and methods for discovery of media items through descriptors

A computer system associated with a media-providing service, comprising:

• one or more processors;
• and
• memory storing one or more programs, the one or more programs including instructions for:
• generating, without user input, a first playlist of media items from at least a personalized pool of media items personalized for a first user, wherein each media item in the first playlist of media items is selected for the first playlist of media items based at least on an association with a first text descriptor;
• causing an application associated with a media-providing service, executing on a client device of the first user, to concurrently display a plurality of text descriptors including the first text descriptor;
• detecting a selection of the first text descriptor, and responsively causing the application to playback at least some of the media items in the first playlist;
• while playing back at least some of the media items of the first playlist, displaying one or more text descriptors as user-selectable options, wherein the one or more text descriptors displayed as user-selectable options are distinct from the first text descriptor, wherein the one or more text descriptors are refinements of the first text descriptor and are displayed as user-selectable options that change with each respective media item in the first playlist of media items;
• and
• detecting a selection of a respective text descriptor displayed as a user-selectable option, and responsively providing, to the application, media items from a second playlist of media items associated with the respective text descriptor, wherein at least some of the media items from the second playlist are different from the media items in the first playlist of media items.

A non-transitory computer-readable storage medium storing one or more programs for execution by a computer system associated with a media-providing service, the computer system having one or more processors, the one or more programs comprising instructions for:

• generating, without user input, a first playlist of media items from at least a personalized pool of media items personalized for a first user, wherein each media item in the first playlist of media items is selected for the first playlist of media items based at least on an association with a first text descriptor;
• causing an application associated with a media-providing service, executing on a client device of the first user, to concurrently display a plurality of text descriptors including the first text descriptor;
• detecting a selection of the first text descriptor, and responsively causing the application to playback at least some of the media items in the first playlist;
• while playing back at least some of the media items of the first playlist, displaying one or more text descriptors as user-selectable options, wherein the one or more text descriptors displayed as user-selectable options are distinct from the first text descriptor, wherein the one or more text descriptors are refinements of the first text descriptor and are displayed as user-selectable options that change with each respective media item in the first playlist of media items;
• and
• detecting a selection of a respective text descriptor displayed as a user-selectable option, and responsively providing, to the application, media items from a second playlist of media items associated with the respective text descriptor, wherein at least some of the media items from the second playlist are different from the media items in the first playlist of media items.
