Multi-audio music instruction data from *STEMMA: Song-to-Stem Multi-Audio Reasoning for Large Audio Language Models*,
built from JamendoMaxCaps and the commercially reusable subset of FMA. The in-house dataset used in the paper is not
included.

| | |
|---|---|
| Instances (`main`) | 162,832 = Relation MultiQA 81,416 + Coreference 81,416 |
| Songs | JamendoMaxCaps 69,297 · FMA 12,119 |
| Audio inputs per instance | 2–5 (songs, sections, or section stems) |

## Format

| Field | Description |
|---|---|
| `id` | instance ID |
| `task` | `<relation>_<format>` (29 relation tasks) or `coreference` |
| `question` | prompt with one `<audio>` per entry of `audios` |
| `answer` | target |
| `audios` | audio IDs |

Configs: `main`, `relation_only`, `coreference_only`. Relation MultiQA formats are yes/no, short answer, and
four-candidate multiple choice; Coreference describes 2–4 songs under separate labels.

## Audio

Audio is not included. Audio IDs map to the original tracks (Jamendo / FMA track IDs):
`<corpus>/masters/<track>/<track>-NNN-<section>` (section), `<corpus>/blocks/<track>/<section>/...-<role>` (SCNet stem),
`<corpus>/masters/<track>` (full song). Section boundaries are in `metadata/<corpus>.duckdb`, which also holds track,
clip, and tag metadata; `captions/` holds the full-song captions used by Coreference.
