Not only the energy which broadcast sound gives to the person but also blocking certain thought patterns is why people use songs and television - they don't want to think, they are afraid to be left to themselves. Many people in civilized world have unpleasant thoughts which they repress with the help of television, of tight activity schedule and by leaving themselves no time for thinking. The whole concept of taking time for thinking is foreign to many humans. It actually was foreign to me until recent years. I wasn't able to imagine wasting time on reminiscence, meditation, observation, rest and simply doing nothing. Mostly thanks to Bashar, I discovered great benefits of thinking, meditating and doing nothing. It is not that I have not been thinking, it was only that I was always in a hurry and I didn't see a benefit of doing nothing. Even a concept of rest was foreign to me. I was trying to pack my day as dense as possible, to do as much as possible and to be as efficient as possible. Most of the time I was worried, panicking, predicting worst possible outcomes and acting preventively to prevent worst possible outcomes.
I believe many people live in the state like this, especially in the cities. They are in constant hurry and constant fear and work preventively to prevent possible negative outcomes. My estimate would be that over half of population of earth is in this state.
New Age ideas, taught by Bashar, Abraham-Hicks and others, explain law of attraction, offering a more positive worldview. According to these teachings, it is more practical to focus on positive choices and stop worrying about the negative outcomes. This allows the person to see more positive opportunities. Many New Age Lightworkers follow this advice.
As I said, I found that sound is energizing for many repetitive physical types of work. Washing dishes, cleaning, repetitive production work, digging, and many other works which don't require much thinking are helped by music, especially by energetic music and also by television and radio broadcasts. I also used to listen to audiobooks (from Audible.com) and to YouTube podcasts (audio plus video) and recorded lectures from NIH videos and "The teaching company". Driving work is especially easy with energizing sound.
A part of energizing effect of music, songs and speech is purely physiological, it entrains the nervous system, helps its synchronization and serves as a pace maker. This is likely why people use energizing music while jogging. Another effect maybe supernatural (non-physical).
Next, as I mention, the music and even more so the songs and the speech allows people to forget that they hate their work and their current status in life. People use the expression "I hate my life" which actually means not life as a whole but current state of affairs in life.
People typically do the work they don't like, to get paid and therefore to support themselves. It is rare to find people who like their work and who do what they want. Most of works are dissatisfying because they limit the creative expressions of people, because people see many ways to be more efficient, but their ideas are not welcome by the system, because in most of the works people see that the work that brings money is not very useful to others or often is damaging others.
These are works which are obviously useful to others: Teaching, medical, construction, cleaning, agriculture, production, repair of goods.
These are works which are often damaging to people: military, diplomat, politics, law, sales, advertising, law enforcement. Why are these works often damaging to people?
Military - often harming innocent people and fighting unfair wars. Diplomats - often harming countries and promoting unfair political actions. Politics - promoting deception, unfair political actions, helping unfair actions by MIC. Law - lawyers often help unfair actions and harming innocent people. Advertising and sales are often based on deception and harm people by enticing them to buy goods and services which they don't need or for the prices which are unfair. Both advertising and sales are responsible for spamming which jams communication channels of people and damages communication and judgment in the society. Law enforcement is a necessary evil, but people working in it, daily face the need to harm people physically and emotionally without knowing who is right and who is wrong.
These are also many in-between works where the usefulness is diverse and questionable. Some of these works are science and research and development. Since the whole society is in crisis, science and development are also in crisis. Good ideas and necessary directions of research and development are repressed by the system, while meaningless and excessive works are funded and supported. Most obvious of those is overmedication of people in civilized countries. Overmedication is unfairly promoted by the establishment, it is obviously wrong and is promoted for reasons of financial gain; and scientists are implicated in the support of overmedication.
So it is very common for people at work they hate to silence their dissent with sound to be more productive and to get through the work day.
In addition, the propaganda they hear on television and radio is helping them to make peace with their position and life, get approval from the broadcasts, put themselves in the context of the town, state and country, to synchronize themselves with others and get psychological relief through that.
