In the season 1 finale of Rapunzel’s Tangled Adventure, King Fredric locks Rapunzel in her room until further notice. While in her room, she sing the song we are going to talk about, set yourself free.
The song has a nice tune to it. It is like Rapunzel looking back at her mistakes and learning from them to (duh!) set herself free.
The song has multiple flashbacks to previous episodes. Some episodes include “What the Hair?!?!, Tangled Before Ever After, Under Raps, Rapunzel’s Enemy, and Queen for a Day.”
