Critical reception
In 2014, Clem Bastow from The Guardian said "'!' is unmatched: it's a towering slab of electronic fuzz, tailor made for giant stadiums and the sort of raves that bring to mind The Matrix's Zion scenes, and yet the song is about staying home and listening to records in the living room with your significant other." In 2015, the song was listed at number 60 in In the Mix's 100 Greatest Australian Dance Tracks of All Time with Nick Jarvis saying "The best track on the album (and arguably the best track the 'Gurge has written yet) – a dance track played by a live band about how dancing around your living room with bae wearing ugly pants is so much better than going out to loud, smoky clubs.". In 2019, Tyler Jenke from The Brag ranked Regurgitator's best songs, with "!" coming it at number 1. Jenke said "Ask anyone from the era, and they'll all agree that '! (The Song Formerly Known As)' is Regurgitator's finest moment.. it managed to become their shining glory, with lyrics that describe just sitting back and avoiding clubs, raves, and concerts in favor of a comfy lounge room in suburbia." calling the song "an essential piece of Aussie music history."
