Organizing Playback with a Smart Queue:

Capability	Description	Benefits
Blending Different Musical Contexts	Allows several smart playlists with different selection criteria, moods, and playback rules to be combined (for example, mixing the playlists "Joy and Energy" and "Calm and Contemplation").	Reduces the effect of monotony during long listening sessions. The musical flow organically combines different genres, moods, and thematic categories, so the listening experience remains varied, dynamic, and engaging over time.
Creating Musical Narratives	The user can define rules for alternating tracks and playlists (for example, two tracks from playlist A, one track from playlist B, one track from playlist C, and then the cycle repeats).	Enables the creation of a musical narrative. A listening journey can be designed (for example, starting with energetic music, moving to calm music, and returning to energetic music).
Maintaining the Desired Atmosphere	Provides precise control over the balance of the queue: the program automatically alternates musical works in the queue with different ratings (5, 4, and 3 stars), emotional characteristics, and notes.	Ensures comfortable background listening. Prevents jarring shifts in quality or emotional mood between tracks. Helps maintain the desired atmosphere.
Customizable Playback Rules	The queue can be fully customized by the user through individual parameters for sorting, shuffling, and limiting the number of tracks drawn from each source playlist.	Provides full control over the structure of the queue. Makes it possible to flexibly adapt playback to the user's current tasks, preferences, and mood.
