Dreaming in Public and Closure are the best to me. The last 2 minutes of Closure are the most thrilling. It sounds like you're running against the clock to escape the ruins of your digital city.
It's hard to pick one favorite. I love My Idea of Fun, because of the lovely "fuck <insert evil here> cause we're enough..." and I love the energetic "Fuck Shit Up". These songs are so meaningful and fun... and they were sang with heart.
