[4] On this song Andrew Vanwyngarden expresses his feelings towards social networking and directly references to a popular site with the line "stab your Facebook."

Rolling Stone magazine said it "ultimately keeps building until it explodes into a rapturous harmony, breaking into full-out thrash in its waning seconds.

"[6] Pitchfork said the song "features flutes, horns, and about seven different sections that reference doo-wop, old school rock'n'roll, electro balladry, Ariel Pink-style lo-fi, wall-of-Spector pop, and the Beatles at their most high.

"[3] The video for "Flash Delirium," directed by Andreas Nilsson,[7] "lends a visual clue into the maelstrom and chaos of modern times."

In the very beginning of the music video, there is a banner outside the car that reads, "Sue the spider" and "Sink the Welsh," a reference to the lyrics at the end of the song.
