I love music but struggle to enjoy new music because I feel like there is a mental block preventing me from consuming new music. How do others in a similar situation deal?

As the title states, I love music, genuinely love music to the extent that I cried openly at the first concert I ever attended. Despite this, I struggle to listen to music I've never heard before even if I really want to and I don't know how to deal with this. I understand that there are some mental health problems that may affect this, and I know for a fact that bipolar and ADHD runs in my family, both of which I think I might have, not to mention I might have NPD although I'm not currently in a safe place to seek a diagnosis. My issue is to the extant I visibly bristle if I hear a musical note I'm not expecting, like a commercial or something of the like. The last time I listened to a new song was three weeksish ago, listening to an REO Speedwagon song, because I liked a song from the same band I'd liked a few months ago.

Despite this, I still like music and mostly consume through accidentally hearing some on TikTok when its unmuted. How can I consume music while navigating being uncomfortable? Is it just a white-knuckle-grip scenario?
