i mentioned this in a previous gym class to someone passively and he was like, you aren't supposed to focus on the music, you're supposed to just let it play in the background naturally. but i don't think he understood me, my point was i saw no purpose or meaning from it, no functional use, it didn't help me in any way and if anything, it just makes interacting and prioritizing harder, like i already have difficulty focusing on one thing at a time in a stable / functional manner, why would i want something that just adds to that?
it's funny how one guy too was like, i need to find a good song before i do my next exercise and in my head i'm like, whatever

listening to music ( out loud ) in general in public when around other people, depending on the song can make me paralyzed or cause me to have psycho motor retardation ( i think i mentioned this in my other post ), unless it's a certain type of song, laid back, low key or "chill" song, in which then it's ok if it is playing in the background and i can then do my own thing and simply be there and function.
also, i read somewhere that this behavior, listening to headphones / earphones may be more "common" in "introverts", i had done some research on this and some people say it's to block outside noise or help their social anxiety, but this doesn't make any sense to me and is counterproductive, if your blocking noise or external stimuli from the environment, all you are doing is making it harder to know what the hell is going on and if anything, this would make things worse, at least for me, i need to have physical awareness of my surroundings, i need to naturally and comfortably have visual awareness and relaxing in the environment just like any normal human being does, if i can't, then of course i can be agitated, stressed and may suffer from avolition, Alexithymia, or other problems.
btw, that social anxiety example i used with the person blocking noise was an INTJ, so that can explain at least partially why i don't relate because i am an ISFJ. i don't see why someone would function like that around others or in public, like it makes sense if you do that alone as a private way of functioning, emotional regulation, etc. it also confuses me because it's the same way with drugs and alcohol, like all these people drink and smoke or whatever around others, like isn't that just asking for trouble, by making yourself more dysregulated, etc, if anything that can cause havok in interpersonal or social settings, but yes, i know you're gonna say, well, it's a social thing or something that "normal" people may do, but i would like to add that IQ ( in my opinion ) AND mbti, are more of the deciding factors, someone with a higher IQ and / or certain mbti type, usually NOT ISFJ will do these things and it does turn out the same way, most, if not all the people i see functioning this way are all different MBTI types AND /or they have higher IQ's than me.
i don't need to get in a debate of IQ, because people will already misunderstand where i am "coming from" or what i mean by IQ, etc. I already have had the same explanations and understanding on IQ, all of which further proove my points as valid, it's not rocket science, but your more than open to share something politely, chances are i'll either compliment it as a good point and / or i will just flat out disagree with you, etc.
