"Lighthouse" is the album’s dark center. The original is produced with ominous, thudding drums. On the Deluxe Edition (often found in the .rar packs labeled "Bonus Version"), the stripped mix removes all percussion. All that remains is a Wurlitzer piano and Kelly’s double-tracked vocal. It sounds like a woman singing alone in a cabin during a storm. It is haunting.
