Music
I've become attached to certain tracks and often can't function outside of my house without singing them, listening to them, or at the very least mentally listening to them. During 2018-2019, and also due to misophonia, I've had to make a specific case to my managers to allow me to wear my earbuds during work to keep my mental state in check. I've since learned to operate by listening to the music mentally, but this is the point we're at now.
There's times I have to avoid songs strictly because I want to maintain a neutral emotional state. As an example, DUET has narrative significance within the game it hails from. I have a difficult time passively listening to the song without being emotionally affected, due to various factors that aren't limited to the narrative, but real-life extrapolations stemming from it. The title theme OMORI has a more severe effect. I've recently had to physically remove myself from a room because I couldn't handle the narrative significance of inadvertently hearing a certain type of ringtone coming from another person's device. Why? You'll have to ask me about that in person.
It really doesn't make any sense. I recognise it as an issue if it's affecting my day-to-day functionality and emotions. I don't like this attachment I have to audio.
