The official Square Enix Music Twitter account has shared a new Theatrhythm Final Bar Line music playlist that was created in partnership with the game's tracklist. It is available on Apple Music, Deezer, Spotify, and YouTube, although the Spotify version may be region-locked.
Theatrhythm Final Bar Line music playlist on services currently includes 52 songs that appear in the base game. Some of the new NieR Automata or The World Ends With You songs have also been included.
So far, Square Enix has only released the Theatrhythm Final Bar Line Season Pass 1 tracklist. That included Live a Live, NieR, SaGa Series Vol 1 and 2, and The World Ends with You Series Packs. It hasn't stated whether there will be a second one or what songs might be included.
Theatrhythm's Final Bar Line is now available on Nintendo Switch and PlayStation 4.
