- Likey is a combination of LOA and TT
- Jihyo doesn't sing the hook. Neither do Sana or Tzuyu, since it's a different person from Signal.
- Momo did the choreo for the dance break.
- Around 2:00 is the best part where they talk about how different their reaction was to Signal compared to Likey. They don't outright say they hated Signal, but I think Jihyo's laugh is very telling of what she thought of it originally.
