Blowouts play the entirety of "Final Voyage" from the Outer Wilds soundtrack. supports adding more. (now works for 1.5.1)
Here's a link to a shoddy gameplay video with it: Youtu.be

1.2 & 1.5.1: The script now checks for more files named "blowout_music" with a number appended like blowout_music1 or blowout_music15 (It shouldn't matter what numbers but I did cap it at 50) and picks a random one to play each time. it still only comes with final end times as blowout_music0.
