Some type of music listening is done alone. Other genres social.
It's not one OR the other, it's one AND the other.
And it depends too; there are people who can fit your inner chords for the music that turns you on; say International, smooth special jazz, chamber classical, Opera (my Dad), French singers (my Mom and family), ... but there is a special place for each person where socially the music is intoxicating, and alone deeply emotional. It's in the majority of people, if not all...it's an evolution, an apprentissage that comes with each one's own time.
I know some classical lovers who are very peaceful people.
I know hard metal rockers who can break your heart without realizing.
Music is a social sport...dance with friends and families
Music is a relaxing sport...enjoying a mountain hike with headphones, or surfing the waves or working the graveyard shifts ...
For two people @ home it's with a couple or friends who enjoy the same music genres.
There were periods in life when social music took precedence, and others when solo listening was the main emphasis. There is tremendous power when the music is shared and everyone is on the same wavelength. Bob Dylan loves playing live because of the sharing communication with the audiences. Live music is social; the musicians play a message, a tune well liked and it fits a gathering of people.
When partying among friends we all have requests, when alone in the home we vibrate to the music that gives us the best emotional beats of our own life in tandem...accord, harmony.
For me personally it's opera, jazz from the ECM label, classical multichannel, blues, international dance rhythm happy tempo. ...everything from the Stones, Beatles to Van Morrison and John Coltrane.
...Alone or together, it depends. ...Of the moment and predisposition to feel @ ease.
