Yahoo - Adele just made her huge comeback and greeted us again with "Hello", her first single in three years that earned 1.6 million plays in an hour. People seem can't get over the emotional, moving song as fans continue to talk and repost about it all over the social media world.

We can't blame them if the music video got the highest number (i.e. 27.7 million) of views on Vevo in 24 hours. It was the fastest video recorded to reach 100 million views.

Why did we easily fall in love with Adele and her "Hello"? It is easy to say that the song just touched our hearts but apparently science has an explanation for this. According to media expert Chris Ferguson, PhD, an associate professor and chairman of Psychology at Stetson University in Florida, there is actually a formula for this phenomenon.

At some point, genetic makeup and personality development can be blamed for people's musical preferences. Extroverts may have preferred type of music while cleaning that will be different from an introvert.

Moreover, a study published by the British Psychological Society proved that factors like personality and IQ affect how people use music in their lives. It was found in the research that individuals with higher IQs and were more intellectual tended to use music in a rational way; while, the introverts and more sensitive used music to regulate their moods. As Ferguson described it, music is a social event-we beging to associate certain songs with certain things.

With this being said, Ferguson explained what made people get hooked to Adele. In his opinion, Adele shows the more suppressed sides of people and shows it is still possible to have loud emotions kept inside despite contradicting appearances. Her songs often narrate loss and relationships-which for sure many listeners can relate to. What adds to this is Adele's universal appeal with her good looks, talent and star quality. Same explanations go for Taylor Swift and her songs as well.
