Music Takes Effect for Fun Brain

According to a study published in January by Valorie Salimpoor neuroscientist at the Montreal Neurological Institute, music can activate the same brain circuitry as when we enjoy food and sex.
Participants listened to the songs of their choice in PET scanners, which detect the release of the neurotransmitter dopamine comfortable feeling, and also performed in the fMRI scanner, which measures brain activity. 
The scans showed that prior to a pleasant feeling in response to music, the listener suffered a surprise near the striatum frontal dopamine, a brain region in anticipation of stimulation, followed by a flood of dopamine in the striatum back, where the brain's pleasure center. "It's like you are addicted," said Salimpoor. 
That the cycle of desire is what meyebabkab addiction and feelings of pleasure.
Of course not all music is created equal, biologist Nick Hudson from the Commonwealth Scientific and Industrial Research Organisation in Australia wondered what differentiates the ordinary songs with a timeless song. He proposes that one key difference may be found through lossless compression, which exploits repetition in music to encode audio data in fewer bits without losing content. When Hudson comparing contemporary and classic hits that have been compressed, he found that the pop, rock, and techno is compressed to 60 or 70 percent of its original size, while classics such as Beethoven's Third Symphony, only 40 percent.

He suspects that the appeal of the classics' may originate from a hidden simplicity. Composers who want to create their immortal works, might do well to create a work that sounds complicated but is actually built on a simple pattern.
