Is there any reason as to why the soundtrack on steam is only 10 tracks / 25 minutes?

It was communicated that "the soundtrack" would be coming to steam, and not "a small amount of the soundtrack" so naturally I expected a simple copy/paste of the full soundtrack onto steam, but uh.. I guess that's not the case?

Being able to listen to any of the tracks outside of the game would've been great, but only 10 were uploaded? This is so disappointing. What's the point of putting this for sale when it's so unfinished?

When it was announced that the soundtrack would be given to Livonia owners I thought hey, that's a really cool way to give a little something to those players that purchased it before it became free, very cool of BI, but it's seriously just 25 minutes? Isn't there already 70 minutes of it implemented in-game and a total of 2-3 hours in the files? what the hell?

Now it feels like that was just fake PR talk in order to calm down any angry Livonia owners, as what was delivered in the end was essentially nothing.

To be honest I feel bad for anyone that purchased it with $$ without realising that they aren't getting the full product. Maybe I'm delusional but if I were to go onto a store page for a soundtrack I would expect that I am purchasing the full thing and not a small fraction of it.

Sorry if I sound like an ass but this is genuinely baffling and disappointing.
