It’s no secret that many students love music. Whether on your way to class, heading to the gym or hanging out with your friends, music just makes you feel good. Depending on the style you choose, it can give you energy or calm you down. Here are some other important reasons for listening to music.

Childhood memories. No matter how old you are, you will always remember a song from your past. Many people keep in mind a piece of music, or a number of pieces, from their childhood. Often when you hear that song, you begin to think of particular childhood memories, such as the song Old Houses in My Hometown. Music can bring back memories you may have forgotten.

Concentration development. Listening to music helps you develop your powers of concentration, especially when you are learning to play a musical instrument. This focus will also be useful in everyday life. You will concentrate deeper in school lessons, or even just in a simple conversation.

Motivation. Often , a song playing on the radio or from a CD will remind you of a situation you are experiencing. Sometimes just listening to that song can give you motivation to get through the situation at hand. Music can often touch us more deeply than words and makes us ready for a challenge.

Encouraging creativity. Music is a creative work of art. Though not everyone who listens to music becomes an artist, people listening to music are likely to feel more creative in the task they are doing, such as writing, painting or even cleaning the house.
