The news programs and music that you heard were the result of radio waves being broadcast out into the air above the area you live in. The answer is waves. A waves is a disturbance that transports energy, not matter, through a system. There are many different types of waves. One, that we are particularly interested in, is called a mechanical wave.
Mechanical waves involve disturbances of a mechanical medium such as air, water, earth, and space.
The propagation of a mechanical wave is easily demonstrated by sound waves created when a person talks. When a person speaks, vibrations in their throat create disturbances in the air in the form of sound waves. The sound waves continue to make disturbances as they travel. These disturbances are picked up by hairs in your ears and amplified, or increased. The result is the sound that you and others hear when someone is talking.
