TikTok audio trends, video loops, "refrain"
Alexander Cho writes in "Queer Reverb: Affect, Tumblr, Time" that, "[r]efrain is repetition, a scoring of affect fed back on itself, a way of apprehending that is not beholden to straightforward formulas of signification" (51). The refrain allows a "flow of affect" (Cho 44) to occur "between elements devoid of so-called natural affinity” (Cho 51).
Viral audios on TikTok perform this linkage between content that would otherwise lack any natural affinity. Often, the affect signified by a song carries the message of a video, allowing the viewer to read how they are supposed to feel about what is being depicted.
The TikTok mobile app automatically replays videos from the beginning until you scroll to another one, and this has led creators to make scripts for videos that logically loop back on themselves, so that you can almost not realize your back at the beginning. If you put your phone down with a video playing, you will be subjected to an "incessant refraining" (Cho 51) of audio-- ironically, this instance of refrain might actually interrupt the flow of affect that one experiences as a TikTok user.
