Is there a way to get the expansion music?

I bought the Planetfall OST and really enjoy the tracks that are provided. Now that I've moved out of the vanilla campaign into the DLCs, I'm hearing tracks that weren't part of the OST. I'm assuming these were released with the various expansions (there appear to be music folders inside some of the DLC folders).

Some games like Stellaris update the OST package when new DLC adds music. Some games sell expansion soundtracks separately. I'm honestly fine with either, but is there a way to legally get these tracks?

Stellaris got a living OST that gets updated with releases. The Planetfall OST only got the music of the base game. This is something people have point out since Revelations, casually
