YMMV: Warning Forever
- Crowning Music of Awesome: The warning siren you get when the next boss is about to show up. It really gives the feel of "Oh f*** oh f*** oh f*** BATTLE STATIONS!" May overlap into Most Annoying Sound to some.
- In addition, you can adding your own favorite background music by converting it into an Ogg Vorbis file and renaming it "bgm.ogg". Of course, that music has to be awesome at least to you for this trope to apply.
