This mashup just might be about the downfall of society...
Is "Pale Shelter" by Tears for Fears about childhood neglect? Is "People Are People" by Depeche Mode about human conflict and those who lack empathy? Is "Cities in Dust" by Siouxsie & the Banshees about how a catastrophic event can change things in an instant?
If all of these things are true, then some kind of meaning begins to take shape when they're combined...
