# 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.

### Operators
|
||
|
||
Here's a table of operators you can use in your Smart Playlists:
|
||
|
||
| Operator | Description | Argument type |
|
||
| ------------- | ------------------------ | ----------------------------- |
|
||
| is | Equal | String, Number, Boolean |
|
||
| isNot | Not equal | String, Number, Boolean |
|
||
| gt | Greater than | Number |
|
||
| lt | Less than | Number |
|
||
| contains | Contains | String |
|
||
| notContains | Does not contain | String |
|
||
| startsWith | Starts with | String |
|
||
| endsWith | Ends with | String |
|
||
| inTheRange | In the range (inclusive) | Array of two numbers or dates |
|
||
| before | Before | Date ("YYYY-MM-DD") |
|
||
| after | After | Date ("YYYY-MM-DD") |
|
||
| inTheLast | In the last | Number of days |
|
||
| notInTheLast | Not in the last | Number of days |
|
||
| inPlaylist | In playlist | Another playlist's ID |
|
||
| notInPlaylist | Not in playlist | Another playlist's ID |
|
||
|
||
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}
