I think the music you listen to can affect not just your specific word choices, as you describe, but also your whole personality. Music is designed to make you feel different, and when you feel different, you act differently. You gradually start to express yourself in ways that have the same emotional effect as the music you listen to. If you had someone listen constantly to Led Zeppelin, Nobuo Uematsu, and Justin Bieber for one month each, I think he would behave differently at the end of each month. And I think that behavior would match up subtly with the emotional impact of the music.
People who disagree with me have argued that I got the causation backward. Maybe the music someone listens to can predict his personality, they argue, but that is just because certain personalities choose certain types of music. For example, if you pick out a stereotypical sorority girl at a liberal university, I imagine there’s a near-100% chance she likes Lady Gaga. If you forced her to listen to Radiohead for a month, some argue, she would still be the same person afterward.
There is some truth to that, but I am still convinced that in the right circumstances, music can subtly reshape how you act.
