Explanation
The lift is real and small, and the window is short. Audio-driven trends typically run for about two weeks, which means a sound you noticed because it was everywhere is a sound you are already too late for. Structural format trends, like the single-take or the reply-to-comment, run for months and are worth far more attention.
There is also a cost that gets ignored. An account built entirely on trending audio has no identity to fall back on when the trends move, and it reads as being behind whenever the timing slips.
The common mistake
Building a video around the sound. Videos that fit a trending audio work; videos that exist because of one are transparent and age badly within days.
