“Dynamite” also generated a sizable buzz on streaming services, with more than 500,000 people pre-saving the track on Spotify—a new record for BTS—according to HITS Daily Double. Pre-saved songs and albums appear in listeners’ Spotify libraries as soon as they become available, and they reflect a strong stream-to-engagement ratio. Spotify filters out “low-quality” streams that come from looping a song, playing it on mute or purchasing plays from a click farm, so a hefty number of pre-saves ensures that those streams are counted as legitimate.
