A British band "Marconi Union" has worked with sound
therapists to create a tune described by scientists as the "most relaxing
song ever". Sound therapists were able to rate ten of the most relaxing
songs, with Marconi Union's 8 minute trance-inducing tune,
"Weightless", coming out on top thanks to its continuous rhythm of 60
BPM, an ideal tempo for synchronization with the heart and brainwaves, making
it an ideal audio accompaniment for a good night's rest.
