All of the music from the Sengoku Basara anime OSTs are now available to stream through Spotify. Originally released in 2009, the first animated series consisted of two seasons and a movie, The Last Party. This also includes music from Sengoku Basara: Judge End or Sengoku Basara: End of Judgement. All of the music from the Sengoku Basara animated series is now available to stream via Spotify internationally with the exception of a few songs. [Thanks, AniPlaylist!]
For anyone unfamiliar with the Sengoku Basara OST, Attack on Titan composer Hiroyuki Sawano scored the first two seasons of the anime and the movie. And for the most part the series has remained dormant, only resurfacing with the mobile game Sengoku Basara Battle Party and with the release of a special fifteenth anniversary edition of the Japanese exclusive Sengoku Basara 4 Sumeragi.
As mentioned above, not all of the music on the original soundtracks will be available to stream. In some regions, the openings for the Sengoku Basara anime are not available. However, all of the tracks composed by Hiroyuki Sawano are available for fans to listen to at their leisure.
The Sengoku Basara anime loosely followed certain story lines within the games. The Sengoku Basara series is a musou title similar to the Dynasty Warriors series, but is set in the Sengoku Period and features famous warlords like Masamune Date, Yukimura Sanada, and other prominent historical figures.
