Background

"Writing-wise, production-wise, we just killed that shit. I didn't really realize how good of a song it was like at the time until it really aged and I really paid attention to how people reacted to it. A lot of people sleep on that song; it's my old sound."

Composition
A piano-driven song, "Knock Knock" serves as a warning of SoFaygo entering the music industry, with lyrics about catching his enemies off guard.

Over the next two years, the song became widely used in videos on TikTok, leading to SoFaygo's rise to fame. It also garnered over 16 million streams on SoundCloud and 32 million streams on Spotify.

Critical reception
DJ Booth commented on the song, "Faygo sings every line of 'Knock Knock' with the confidence and clarity of a pop star, but, like so many of the scene's creations, his vocals feel stitched together, rough around the edges. The beat, too, has that handmade quality—a see-sawing MIDI orchestra courtesy of Lil Tecca, an underrated producer whose credits run rampant through Faygo's corner of online rap." Natalie Maher of Elle included the song in her list "The Best Songs on Tiktok to Listen to in Full".

Music video
The official music video was directed by Cole Bennett and premiered on May 3, 2021. It was inspired by the film Beetlejuice.
