Not satisfied with just being the kingpins of pop-punk, blink-182 have conquered other genres as well. The presence of Alkaline Trio's Matt Skiba gives "Sober" an emo vibe, while the whirling "Ghost on the Dance Floor" and "Even If She Falls" hint at '80s college rock. Co-vocalist Mark Hoppus and drummer Travis Barker even created synth-flecked New Wave in their side project +44.
