Billie Eilish and BTS music among the most listened to for falling asleep, according to a study

Danish researchers have analyzed more than 225,000 tracks on Spotify to determine which songs are most used by listeners to fall asleep.

Without knowing it, Billie Eilish, BTS and Khalid are among the artists who help many people fall asleep every night. In a study published in the journal PLOS Oneresearchers from the University of Aarhus in Denmark have tried to compile a list of the most used songs for sleeping.

To do this, they analyzed more than 225,000 songs, taken from 985 playlists related to sleep on Spotify, in order to better understand the characteristics of the most listened to songs and to find any common points between them.

Although they found that, quite obviously, the music used for sleeping is mainly characterized by a calm tempo and instrumental and acoustic melodies, these researchers were nevertheless surprised to find among the most listened to pop and rap.

The preferred BTS for sleeping

The study specifies, for example, that out of all the data analysed, the song that returned the most in Spotify’s sleep playlists is Dynamite by the South Korean K-pop group BTS, which appears 245 times, despite its characteristics far removed from relaxation songs.

Other popular titles such as jealous of Labrinth, or lovely by Billie Eilish and Khalid have also returned numerous times to Spotify’s sleep playlists.

According to Kira Vibe Jespersen, an assistant professor at Aarhus University who participated in the study, interviewed by euro newspeople who listen to this type of music “would seek to regulate their emotions before falling asleep, to distract themselves or to mask the sounds of the external environment, such as the noise of traffic, a neighbor or other.”

“The study clearly shows that there is no ‘one size fits all’ when it comes to music for sleep, and it underscores the importance of considering individual preferences when choosing music for sleep” , added the researcher on Twitter.
