I'm putting together a soundtrack composed primarily of popular music for a zombie film. The movie is set in the Idaho wilderness. The zombies are fairly ordinary by today's cinematic standards; the intent is to focus more on the group dynamics and maintaining (or losing) one's humanity. Anyhow, what I need help with is song selections. I need pieces that evoke anger, paranoia, tension, hopelessness, essentially negative feelings. I'll need soft & slow songs, loud & intense music... So I'm open to many different suggestions. So whaddya got?
