I mostly listen to stoner and doom bands such as Elder, Om and Electric Wizard.
Really fits driving down a road at sunset in a battered up vehicle with burning buildings and piles of corpses everywhere.
Blue Oyster Cult also goes down that road.
If i find alot of drugs and military stuff i put on Rings of Saturn, because nothing fits slaying aliens with hitech weapons while pumped up on psychadelics than virtous scala wankery over really awesome 8 string riffs.
On the other hand, if i find an SKS, i put on my Red Army Choir playlist(wich starts with V Put) and march around liberating the world from its capitalist atrocities!
