Awesome Music: Lots, notably "Falls Apart", "Step to Me", "Welcome to the Masquerade" and many more.
Dork Age: It's too early to tell, but Oxygen:Inhale seems to be becoming this.
Heartwarming Moments: One for the fanbase, so a sort of meta-example. The band has managed to gain a devoted fanbase of people who aren't Christians or believers at all in addition to all their fans who are. All united by their love of the band.
Periphery Demographic: Despite being a Christian Rock band, they've got a lot of fans who aren't Christians, or fans of Christian Rock. It's gotten to the point where every odd comment is "I don't believe in God but this music is awesome, shut up about religion and rock out" on most of their YouTube videos.
