Taylor Swift is known for hiding messages in her album digi-packs by capitalizing unnecessary letters in song lyrics, such as spelling out "WROTE THIS INSTEAD OF CALLING" in the song "I Almost Do" from her album Red. These hidden messages provide insight into Swift's songwriting process and promote fan engagement by encouraging fans to actively look through the digi-pack for the hidden information. This technique inspired the author to include hidden messages in their own digi-pack as a way to encourage exploration of the booklet and please dedicated fans.
