Are you stressed out? Maybe you should try music therapy.
This song by Marconi Union was composed in collaboration with sound therapists, and carefully arranged so that its "harmonies, rhythms, and bass lines help slow a listener's heart rate, reduce blood pressure and lower levels of the stress hormone cortisol."
Researchers say listening to this song will reduce your anxiety by 65%.
