The Starbound sound track is really amazing, it includes rhythmic soothing patterns in most of the music. Other than that, it includes a wide variety of music, which I enjoyed immensely. It also includes some expieriemental more electronic tracks, but those aren't as well made.
If you like more synthy, piano, and strings, I definitely reccomend this soundtrack.
Expierimental - 7/10
Others (Including tracks 43 and 44) - 9/10
I don't know about other computers but for mine I had trouble finding it. Using this method, I was able to fix this problem. If you right click Starbound in your library, and hit properties, it will bring you to a window with multiple tabs. Go to the DLC tab, and then uncheck install and recheck it. It should say theres an update. If you download that, it will work. If that doesn't, go to the search window and go to programfiles X86, Steam, SteamApps, common, and then Starbound. In there there should be a folder titled Starbound Complete OST. All the tracks should be there.
If it doesn't work, comment and I may be able to help.
