I tried to find this Song too... But it's so difficult. Searched for dubstep, darkstep, dubchestral, dubstep with gregorian chants.... but I didn't find anything. And yeah, Pewdiepies answer in the video-comments made me a bit angry.... (100% Sandstorm) What's wrong with you Felix? You're not still the same at the moment. Please come back how we like you *brofist*
