What is the song on the PBE launcher log in screen right now?

Opened PBE launcher because the regular game is down for maintenance and heard a new song that I really like but I looked up most of the lyrics and still can't find it anywhere. It seems like it would be called "We came here to fight" but haven't found anything close searching that. Some of the lyrics in the chorus: "Fight! Who's next in line? Can you make that climb? Now is the time! Get outta your mind! Raise up the lights, we all here tonight, so lets do it right, yo we came here to fight!". This song is getting me really pumped so I'd like to get it on my spotify or youtube or something but it's nowhere to be found. If anyone knows what its called and the artist let me know. Thanks!
