# Navidrome Smart Playlist documentation:

Smart Playlists in Navidrome offer a dynamic way to organize and enjoy your music collection. They are created using JSON objects stored in files with a `.nsp` extension. These playlists are automatically updated based on specified criteria, providing a personalized and evolving music experience.

## Creating Smart Playlists

To create a Smart Playlist, you need to define a JSON object with specific fields and operators that describe the criteria for selecting tracks. The JSON object is stored in a `.nsp` file
Here are some examples:

### Example 1: Recently Played Tracks

This playlist includes tracks played in the last 30 days, sorted by the most recently played.

```json
{
  "name": "Recently Played",
  "comment": "Recently played tracks",
  "all": [{ "inTheLast": { "lastPlayed": 30 } }],
  "sort": "lastPlayed",
  "order": "desc",
  "limit": 100
}
```

## Example 2: 80's Top Songs

This playlist features top-rated songs from the 1980s.

```json
{
  "all": [
    { "any": [{ "is": { "loved": true } }, { "gt": { "rating": 3 } }] },
    { "inTheRange": { "year": [1981, 1990] } }
  ],
  "sort": "year",
  "order": "desc",
  "limit": 25
}
```

### Example 3: Favourites

This playlist includes all loved tracks, sorted by the date they were loved.

```json
{
  "all": [{ "is": { "loved": true } }],
  "sort": "dateLoved",
  "order": "desc",
  "limit": 500
}
```

### Example 4: All Songs in Random Order

This playlist includes all songs in a random order. Note: This is not recommended for large libraries.

```json
{
  "all": [{ "gt": { "playCount": -1 } }],
  "sort": "random"
  // limit: 1000 // Uncomment this line to limit the number of songs
}
```

### Example 5: Multi-Field Sorting

This playlist demonstrates multiple sort fields - songs from the 2000s, sorted by year (descending), then by rating (descending), then by title (ascending).

```json
{
  "name": "2000s Hits by Year and Rating",
  "all": [{ "inTheRange": { "year": [2000, 2009] } }],
  "sort": "-year,-rating,title",
  "limit": 200
}
```

### Example 6: Library-Specific Playlist

This playlist includes only high-rated songs from a specific library (useful in multi-library setups).

```json
{
  "name": "High-Rated Songs from Library 2",
  "all": [{ "is": { "library_id": 2 } }, { "gt": { "rating": 4 } }],
  "sort": "-rating,title",
  "limit": 100
}
```

## Troubleshooting Common Issues

### Special Characters in Conditions

If you encounter issues with conditions like `contains` or `endsWith`, especially with special characters like
underscores (`_`), be aware that these might be ignored in some computations. Adjust your conditions accordingly.

### Sorting by multiple fields

You can sort by multiple fields by separating them with commas. You can also control the sort direction for each field by prefixing it with `+` (ascending, default) or `-` (descending).
Examples:

- `"sort": "year,title"` - Sort by year first (ascending), then by title (ascending)
- `"sort": "year,-rating"` - Sort by year (ascending), then by rating (descending)
- `"sort": "-lastplayed,title"` - Sort by last played date (descending), then by title (ascending)
  The global `order` field can still be used and will reverse the direction of all sort fields.

##### Notes

- Dates must be in the format `"YYYY-MM-DD"`.
- Booleans must not be enclosed in quotes. Example: `{ "is": { "loved": true } }`.
- `filepath` is relative to the music library folder. Ensure paths are correctly specified without the `/music` prefix (or whatever value you set in `MusicFolder`).
- Numeric fields like `library_id`, `year`, `tracknumber`, `discnumber`, `size`, `duration`, `bitrate`, `bitdepth`, `bpm`, `channels`, `playcount`, and `rating` support numeric comparisons (`gt`, `lt`, `inTheRange`, etc.).

##### Special Fields

- `random`: Used for random sorting (e.g., `"sort": "random"`)
- `value`: Used internally for tag and role-based queries

##### MusicBrainz Fields

The following fields contain MusicBrainz IDs that can be used to create playlists based on specific MusicBrainz entities:

- `mbz_album_id`: Filter by specific MusicBrainz album
- `mbz_album_artist_id`: Filter by specific MusicBrainz album artist
- `mbz_artist_id`: Filter by specific MusicBrainz artist
- `mbz_recording_id`: Filter by specific MusicBrainz recording
- `mbz_release_track_id`: Filter by specific MusicBrainz release track
- `mbz_release_group_id`: Filter by specific MusicBrainz release group

##### Additional Fields

You can also use these fields in your Smart Playlists, they are highly recommended as they are generated using sonic analysis on each song:

| after         | After                    | Date ("YYYY-MM-DD")           |

The nature of the field determines the argument type. For example, `year` and `tracknumber` require a number, while `title` and `album` require a string.

# Process:

1. Ask up to 3 quick clarifying questions only if necessary
2. If info is sufficient, produce the final playlist json.

# Output format (strict):

Output the generated smart playlist rules json as well as a short and simple justification for each rule below. Ensure the playlist has a name and description.

# Guidance:

- Keep it concise; avoid prose outside the specified fields.
- Feel free to chain and nest `all`'s and `any`'s (series of ANDs and ORs respectively), but remember to keep the playlist rules minimal to avoid an empty playlist

# Input:

{enter your desired playlist here}
