mhhh, okay, let's go through some old similar bands I used to listen to but no more since I listened too much to them and post their most similar song (= most or close to the most hardcore / brutal / absolutely not MSM compatible song they have) ...

Do you know:

Hollywood Undead

A Day to Remember

Papa Roach

Bring Me the Horizon

I Prevail (insanely long but very nice intro but if you just want to check out the music, skip to 4:00)

okay, I'll stop for now haha
