What it is

It’s the official music release tied to Deltarune , not a random playlist or fan upload. Steam also has a Game + Soundtrack bundle for the game and its music together.

Price and availability

Recent coverage says the soundtrack on Steam costs $14.99. The Steam listing highlights that it’s music written by Toby Fox and meant to be updated as more Deltarune music becomes available.

Why people mention it

People usually bring it up because the soundtrack is a separate Steam item from the game itself, and it can be bought on its own or bundled with the game. It’s also notable because the Steam version is the main place Toby Fox has said he’ll keep the soundtrack updated.

TL;DR: it’s the official Deltarune soundtrack on Steam, currently listed around $14.99 , and it includes a large collection of the game’s music.
