A professor in cognitive psychology and neuroscience recently teamed up with Spotify to try and figure out what is the most scientifically romantic song, and together they decided that Adele's cover of Bob Dylan's 'Make You Feel My Love' has to be it. 

Referring to the song specifically, scientist Jacob Jolij explained his theory that the perfect formula includes "sentimental lyrics, a slow tempo, syncopated rhythm, in a major key and standard chord progression": 

"'Make you feel my love', you clearly hear the syncopated rhythm in the melody - it's (approximately) ONE - and - two - and - THREE - and - four - AND - ONE - and - two - and - THREE - and - four - AND - ONE - and etc."

"You see that there are two accents close together, repeating every bar. This creates the feel of a relaxed heartbeat. Some researchers believe this is the reason why these rhythms have a soothing and relaxing quality."

Other tracks that made the Top 10 in time for St. Valentine's Day include Marvin Gaye's 'Sexual Healing' (No. 2), Elvis Presley's 'Love Me Tender' (No. 5), and Passenger's 'Let Her Go' at No. 6.
