### App version

Production

### Issue description

When selecting the Smart Filter “is a single - true”, the app returns no results.

I have many tracks tagged with Release Type “single”.

How does this Smart Filter check if a track is a single? Thanks for the info!

### Device type

Phone

### Media provider

Local device

### Steps to reproduce

- have tracks tagged as “single” release type
- go to Tracks screen
- Smart Filter, add rule: “is a single”, set to “true”

### Additional information

Yes, I know I can use the album Type filter. The track filter seems like it _should_ do the same thing, yet I get no results.

“Is a single” means a track without an associated album—normally one with no Album tag for local files. It doesn’t check the Release Type tag.

A track tagged with release type “single” can still belong to an album, so it won’t match this filter. Your logs confirm that the filter finds no tracks without an album. “Album Type” is the appropriate filter for the release-type metadata you’re using.
