I wish I was better at this sort of thing
If you start this pantheon video at 1:53:48 and then also start the Joan Jett cover of "Dirty Deeds" ( queung it after the ad) the music and the game play seem to fit. Like when Joan Jett sings the refrain of dirty deeds, that is when the Kilsin character sneaks and then tried to hide. Also near the end when kilsin is soloing a mob it also seems to fit.
Also I thihnk the Kilsin chacater kind of looks like Joan Jett at the begining. I wish I was better at this sort of thing to splice it together. instead I opened two windows,one wirth the stream and one with the Joan Jett cover and hit play on stream, then on video.
Start this at 1:53:48

Then start this at begining after ad- try to get as close as possible to timing
