They replace all of the music tracks in space engineers, which is why this mod must be downloaded and manually installed. The download has a readme. Sorry the mod will not work with just the subscribe button, this is a limitation of the tools available. BTW this mod isn't just one large track that plays on loop, I replaced every instance in the game with a different track. Here is the readme: 1.Make a new folder on your desktop. 2.Extract "Space Engineers Retro Music Mod" to that folder. 3.Go to your Space Engineers steam directory. 4.Example:C:\Program Files (x86)\Steam\steamapps\common\SpaceEngineers\Content\Audio. 5.Copy and paste "MUS" into the "Audio" folder. 6.Replace existing. 7.Done! Note:I take no credit for any of the music, this is just a compilation I put together and converted to replace all of the se music tracks.
