I think you were probably right when you said it’s not what you’re listening for. It used to actually and truly confuse me to no end how someone could prefer The Rolling Stones to The Beatles. I believe that musical preferences say a lot about a persons personality and worldview. Many people are primarily focused on their physical being and thrill from feelings derived from various stimulations and challenges to their body. They will often prefer music that is more primal and rhythmic. Also their preference in lyrics might lean towards sexual or violent content. The endorphin rush they crave is what they seek to compliment with music. Those folks listening preference will be quite different from someone whose interests are primarily in relationships and empathy with others. All of the infinite shades of personality influence musical tastes. Then there’s the factor of projecting a persona to others that sends social signals that we think will attract what we want and protect us from what we fear. Musical tastes are deep stuff man.
