This is a DnB song from the Bomberman Hero OST that plays while fighting Nitros. It could be good for boss battles or other high-pressure scenarios. That opening sample is a real mood-setter.
If you need the vanilla death song, restore the "default/0A SMW @9.brr" line and instead empty out other .brr files that you don't need, or replace "default" with "optimized". Inserting this song higher up in the song list (i.e. with a smaller song ID value) may allow you to fit more into ARAM.
