Swxftys song for alerts belongs to the short alert sounds that streamers and editors keep ready for live moments instead of full songs. Clips like this spread through soundboards because they are easy to preview, download as an MP3 and assign to a single action. Its short length makes it practical for repeated use during a busy stream, where longer music would overlap speech or other effects. It stays popular for the same reason most alert stings do: viewers learn the cue and instantly connect it with something happening.
