Once you eat a potato chip, its really hard not to eat more. Thats what i mean, once you hear one of these clips, you can't stop listening to them. As for which part of the sound... I'm not exactly sure what it is but I can tell I will love this album. I'm predicting waiting for the end will be one of my favorites, along with blackout, the catalyst, wretches and kings, burning in the skies and probably the requiem, the radiance, empty spaces, when they come for me, robot boy, jornada del muerto, wisdom justice and love, fallout, and the messenger.
