Secondo una ricerca condotta dal dr. David Lewis-Hodgson, la canzone più rilassante del mondo è Weightless. Il brano è stato prodotto dalla band Marconi Union in collaborazione con la British Academy of Sound Therapy.
Studies found Weightless was 11 per cent more relaxing than any other song and even made many of the women "drowsy" in the lab.
It induced a 65 per cent reduction in overall anxiety and brought them to a level 35 per cent lower than their usual resting rates.
The song features guitar, piano and electronic samples of natural soundscapes.
It is pierced throughout by buddhist-like chants that induce a trance-like state.
