How we make these breakdowns
theIDOL builds every breakdown with AI assistance and automated checks, and publishes a page only after it passes them. An AI model writes the meaning of each line and the word-by-word glosses from the song's timed lyrics. The pronunciation comes from our own rule-based Korean transcriber, which spells how the words sound when sung, sound changes included, not a letter-by-letter romanization. Pages that fail the audio-sync or translation checks are not published, and we quote only a few key lines. If you spot a mistake, write to support@theidol.ai and we will fix it.
