You know that the whole soundtrack is more than just these 4 songs right? There's these full 4 full songs listed in the credits, and there's also additional instrumental music throughout the whole movie by them, pretty much just like the Raid soundtrack. I doubt that they would "waste" the on the LPU14 since they basically would make almost no money from it, and I'm sure they know a lot of people would be interested in buying it, it's still new LP music in some way. I hope that they do at least a digital release.
