There are 2 soundtrack DLCs for Ori and the Blind Forest: Definitive Edition. Ori and the Blind Forest (Official Soundtrack) is the same as the one that you could get as DLC for the original release of Ori, and includes all iconic tracks like “Completing the Circle”. If you own it already you do not need to buy it again as there is no new or different content here. Ori and the Blind Forest (Additional Soundtrack) contains 1) new tracks from the new areas in Definitive Edition, 2) music that was not released on the Official Soundtrack, 3) music from the 3 trailers that Moon Studios created for the game, 4) a selection of music that was unused or cut from the original game, and 5) a selection of music from the original Ori prototype. This soundtrack has only been available on Bandcamp and Youtube to this point. The Official Soundtrack will continue to be priced at $9.99. The Additional Soundtrack will continue to be available here and elsewhere for free. Between the Official and Additional soundtracks, completionists will have just about every cue that is heard in the game.
