Question about a song from "Silence" game(possible spoilers in discussion)

Have you checked the game install directory for audio files? sometimes the audio is totally available without doing anything.

you may need to rip the audio from the game yourself.
set everything but music to 0% volume and record it with something like fraps, then convert to mp3.

not the best thing but it works. ┐(ツ)┌

Reminds me of Ships are Sailing, a traditional Irish tune.

It really sounds like theme from The Secret of Monkey Island: https://youtu.be/i3dB0qEcG20?t=31

Here's a newer version: https://youtu.be/FoT5qK6hpbw?t=49

It also sounds like every pirate's music in every game ever. Like this one: https://youtu.be/EGNz8UJCpbk?t=32

Or this one from The curse of Monkey Island: https://youtu.be/JbWZjfLO2Z0?t=56

The song may not exist anywhere, even in the game files. There are 3 separate instruments that make the song and you can play them one at a time or manipulate them in different ways to make the song sound different. Maybe there are individual sound files for each sound and the game actually composes the music as you play.

Like others have said, you may need to make a recording of the game and then use software to pull the audio from the video file. I don't know much about recording gameplay, but it's not difficult to make an mp3 of the audio once you have a video. I use Pazera audio extractor.

Thanks to all for the suggestions, it seems that is time to replay the game and record that song.
