DELTARUNE Soundtrack
The DELTARUNE Soundtrack is a variety of Deltarune albums that are often released alongside the corresponding Chapters. Much of the music tracks are composed by Toby Fox, with some arranged or sung by guest musicians. These tracks have many recurring leitmotifs, and occasionally are songs with lyrics. Several tracks are used in multiple Chapters, and a few tracks are reused from Undertale.
Toby has described that some of the track names are spoilers, and recommended that players should not read them until after completing the game.[1] Toby has also stated in the official newsletter that the Steam version of the soundtrack will be updated to also include later Chapters' soundtracks for free.[2]

Even if you use other platforms, I recommend buying the soundtrack on Steam. I'll be updating the soundtrack every time a new Chapter comes out, so it'll be a really good deal.
