Maine's Official State song is 'The State of Maine Song' adopted in the 1930s. We love this song but, we like other songs, too. The world has just received a new song in it's list of State of Maine songs called "My Sweet Maine". Governor Janet Mills signed a law on Friday to add 'My Sweet Maine' by Terry Swett to the playlist of great Maine songs. This one has been dubbed, and legally so, 'Maine's Song of the 21st Century'. Give it a listen: The song was written by Terry Swett, a Bridgton songwriter, to honor Maine's 200th anniversary of statehood. In early 2020, Swett unveiled the song at a local Chamber of Commerce breakfast prior to the pandemic lockdowns.
