"We Know The Way" is an important song in Moana as it introduces the audience to the Wayfinders, the ancestors of Moana's people who were great explorers. This song, written by Miranda and Foa'i, is a celebration of their navigational skills and their deep connection with the natural world. It's also crucial in Moana's journey as it rekindles her longing to set sail and encourages her to embrace her heritage.
