Hey Marseilles' "Gasworks"

This morning I listened to Hey Marseilles' To Travels & Trunks.  I've always liked the line "long nights and hollow days" in "Gasworks," but I discovered something interesting about how it's articulated.  There's a slight pause between "hollow" and "days."  Ostensibly, it's there for enunciation.  Otherwise, the words might bleed into each other and sound like "holidays" or maybe even "hallowed days."  So the pause is there for clarity, but the pause also indicates the despondency and numbness inherent in the phrase "hollow days."  It's as if the singer/speaker doesn't have the energy to even describe the days.
