U2's One named as perfect lullaby

Irish rock band U2 is one of the most popular musical groups in the world, estimated to have sold more than 150 million albums worldwide during the course of a recording career spanning four decades and playing to sellout crowds across the globe. But now they have earned an unlikely new honor after scientists judged one of their most popular songs to be the formulaic perfect lullaby.

Researchers in the Music and Science school at Durham University in the United Kingdom teamed up with online music streaming platform Spotify and children's bedding company Cuckooland, looking at 4,500 songs regularly chosen for bedtime playlists.

They ended up selecting the track One, from U2's 1991 appropriately named album Achtung Baby, as the ideal soothing bedtime music.
