Of all the things we might possibly have in common with others, music turns out to be the most accurate way of getting to know someone new.
"Getting to know you, getting to know all about you."
In the iconic musical The King and I, schoolteacher Anna bridges the cultural gap between herself and her Siamese students with the aptly-titled "Getting to Know You." In South Pacific it was the song "Happy Talk" - now a fixture in preschool music time - that helped an American soldier bond with his Polynesian love. We've always known that music bridges the gaps, and helps us to understand each other.
Of course, we're not singing to each other at parties in an effort to identify potential friends (unless they're Karaoke parties,) but most of us have approached a new acquaintance by asking, "What kind of music do you listen to?"
And now science is gathering data that shows that a person's musical taste is a very effective way of, well, getting to know them.
In a great article late last week, the Huffington Post explored the findings of a study conducted with college students that found that they could determine when meeting a new person whether they had friendship potential by first surveying their taste in music.
The reasons why the Music Method of scouting friendship usually works? According to HuffPo, "Music expresses values. Lyrics have social messages." Therefore, you can easily determine that a person who likes the same music that you do will most likely share some of your values.
On a more specific note, you can assume that a musically like-minded person will expose you to new music that you will also like, and that if you become friends and spend time together in the future, you will always have something to talk about.
