Ever hear a song on the radio and feel your mood change almost instantly? Maybe you’re stuck in traffic and worried about being late for a big meeting. Stressful! But then a favorite tune comes on and before you know it, you’re feeling better. Ever listen to the sounds of the ocean when you’re trying to fall asleep? Setting the scene with music for whatever it is you’re doing—meditative music for yoga, upbeat music for a tough workout, or classical music for a stress-relieving soak in the tub—can be the key to helping you achieve your goal.
