I tried to make this song as epic as I possibly could. I pretty much have been doing this whilst I am on lockdown (hence the name) due to this virus outbreak. I thought to venture out for more samples and one of the places I went towards was OpenGameArt.org. I'll list the sources (so you can download them, and also because I need to give credit to the sample creators). Do note that I am a noob at this music creation game
