Panic! At the Disco sound exactly like their friends Fall Out Boy on their fourth album's opening "This Is Gospel," with Patrick Stump-style vocal flicks and "oh-oh-ohs," despite robotic vocoder. Panic! are no longer making retro power-pop with modern bells and whistles. This time around they mimic classic electro-pop, from The Faint ("Girl That You Love") to Devo ("Girls/Girls/Boys"). Head straight to the peppy "Collar Full" for the best melody here.
