We'll fingerprint the full file and try to identify it for you. AcoustID (free) is tried first; if no match, we fall back to ACRCloud (paid). Whichever recognises the song, we then look it up on Apple Music by name to fetch canonical album, year, ISRC and cover art. You'll choose which metadata to commit.
Edit artist/title if misspelled, then click Look up to search providers. Pick a candidate (radio) or paste/type values directly. Save writes only the filled fields back to the track — leave any field blank to keep the current value.
