# Songs that sound like this song

`GET /songs/{song_id}/sonic-match`

Similarity is derived from analysing the audio, which Ampache does not do itself, so this needs a sonic-analysis plugin (see the AudioMuse plugin). With none enabled the request is refused with 403 rather than answered with an empty list. `similarity` runs 0.0-1.0 where 1.0 is the same recording, matching the OpenSubsonic `sonicMatch` scale, and is -1 when the backend gives no comparable score.

## Path parameters

- `song_id` string, required

## Query parameters

- `limit` integer
- `offset` integer

## Response `200`
