I agree, the single is catchy as hell, but I don't really dig the production. The instrumentals are okay, if not a little out of place. I just wish they'd mix their style with more progressive song structures. Seems like wasted potential.
The Swarm and The Descent sound so damn good, if only they were either integrated into a longer song or just elaborated on in general. ~2 minutes just isn't enough time for them to really take off and they could've been outstanding if expanded upon.
