I think this is an issue of word choice. You’re describing something with the word personality that I would describe with mood. Getting pumped up has nothing to do with your personality. Listening to music with high BPMs or strong beats raises your heart rate and excites you, yes, especially if you enjoy the type of music. But this has very little to do with one’s personality. Again, listening to Justin Bieber pop songs isn’t going to make me want to do whatever the music is talking about. And listening to death metal isn’t going to make me want to kill people (not that most death metal is about that but to you it probably is). I will agree with one detail of your claim, however, in that it can make a subtle difference. But I would imagine this is temporary and is more tied to how one is currently feeling rather than how they identify with the world.
Pretty much. Personality is much more embedded within the psyche to be that susceptible to the atmosphere of the music. Mood on the other hand, how one is currently feeling, I can certainly see being tied to music, as it has everything to do with your surroundings. Obviously if I’m feeling down, listening to a piece of music I really enjoy will make me feel better.
