So I watch one of JonTron's older videos recently, "Malkovich's Gaming Game Show", and heard a song playing in the background during the whole shootout starting at 4:20. I remember being able to find the song on YouTube years ago by searching "epic music" or something like that and it was one of the first results. However, after some time had passed, I was no longer able to find it and never saved it to any of my playlists. Shazam or other similar apps/services turn up nothing and I scrolled through miles of comments to find nothing, but maybe 2 people asking about it with no answer. No amount of google searching or digging through subreddits, wikis, and forums has turned up a single thing. I posted to a few other places and haven't gotten anything. If anyone can find anything at all about this song I would be amazed and overjoyed because I haven't found any traces of it anywhere else and it's driving me nuts not knowing.
