“What a tuuune!” – A Scientifically Good Song

It’s a Saturday night, you are about to hit the town. There are many things that can affect how good the impending night out is going to be, the quality of the company, amount of alcohol consumed, making it home with all your possessions. The music also obviously plays a key part in the night and scientists have proved that certain songs can create feelings of euphoria and an almost drug like high, observable in the brain. So what music is scientifically likely to result in a great night out and what is the science behind it?

Dr Valorie Salimpoor and her team based in Canada have done several studies into the effects of music on the brain, she says, “Music has no functional resemblance to other rewarding stimuli, and has no demonstrated biological value, yet individuals continue listening to music for pleasure”. Her latest findings published in Nature indicate that music can create euphoria and craving, similar to “rewards that involve the striatal dopaminergic system”, a system that plays a big role in the feeling of being ‘high’ and drug addiction.

They discovered this by using positron emission tomography (PET) scanning and measuring the activity of the autonomic nervous system. One key factor of a party was taken into account in the study, variations in music taste (note: this may not be a controllable variable on your night out!) with each participant being played genres of music they enjoyed and those that they found neutral.

Although, they were able to study the levels of dopamine released using markers, the feeling of euphoria is quite subjective. So to attempt to circum navigate this they also looked at the physiological feeling of getting a “chill” when listening to a song.

They observed a “temporal dissociation between distinct regions of the striatum” while subjects were listening music they described as pleasurable. They also observed peaks of ANS activity that indicates that the most intense reactions to music are cause by dopamine release in the NAcc, a region has been implicated in effects of such as cocaine.

Another phenomena observed was that before the peak of emotional responses to the music there was greater dopamine activity in the caudate. The causdate region of the striatum plays an important role in memory and stimulus-response associations, potentially indicating that this may be the cause of the associations of particular emotions, feelings and moments with songs.

So what songs are likely to cause these kind of effects? Well another study by the same research group came out with a list of instrumental songs most likely to cause the ‘chill factor’ according to their observations.  They asked their participants to select 3-5 songs which caused the chill factor for them. They were not allowed to pick songs that they had an emotional connection to (e.g. “Aww this our song!”) or songs from films (unless they hadnt seen the film), this was to try to reduce any prior associations with the song. The songs ranged from  from classical to jazz. They were then played songs selected by others and both asked to rank the pleasure they gained from them and were fitted with monitors to record heart rate, BVP amplitude, respiration rate, electrodermal activity and body temperature. The study found that there is a direct link between emotions and music due to an observed relationship between increased levels of emotions and self-reported increases in pleasure. The following are a few songs that brought about these reactions that might be suitable for a night out:

Tiesto – Adagion for Strings

Infected Mushroom – Viscious Delicious

Darude  – Sandstorm
