Hey, congrats on winning second place! I haven't seen either of these films, so I wasn't familiar with the song either, but I agree, it captures the mood very well. That is, the mood you conjured by your vivid description of the plot.
Honestly, I've never been a fan of zombie movies, I always thought they were a bit silly. But now after Covid I think the mere idea is utterly scary! Imagine all those people infected by Rona coming after us... Just the social implications make my hair stand on end. On the other hand, all this would give me even more of a reason to watch 28 Days (and maybe 28 Weeks), and get a righteous fright out of it.
