Evidence claims:
- [upstream_claim] Dataset card: 5,521 music examples, each a 10-second AudioSet clip (2,858 eval split, 2,663 train split) with an English aspect list and a free-text caption written by musicians describing how the music sounds. · locator: dataset card, summary and structure · source: https://huggingface.co/datasets/google/MusicCaps
- [sourced_fact] Distribution is a CSV of YouTube video IDs and start/end timestamps; users must download and cut clips themselves; the card does not host the audio. · locator: dataset card, data fields · source: https://huggingface.co/datasets/google/MusicCaps
- [sourced_fact] Card states 'The license for this dataset is cc-by-sa-4.0'; cites MusicLM (arXiv 2301.11325); supported-tasks and social-impact sections marked More Information Needed. · locator: dataset card, license and citation · source: https://huggingface.co/datasets/google/MusicCaps
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- dataset: license=CC-BY-SA-4.0 hosting=permitted redistribution=restricted modification=permitted training=unknown · CC-BY-SA 4.0 covers the annotations; the underlying YouTube audio is not licensed or hosted by the dataset, so rights in the audio are separate and unknown. · evidence: https://huggingface.co/datasets/google/MusicCaps
