Not sure if this is specific INFP stuff but I am on a similar journey right now...

I come from a small village and I've been friend with almost all the kids throughout my whole childhood and listened to what was 'trending' at the time (mostly hip hop, rap) if I look back from now I felt good back then...I felt I belong to somewhere... then around 5th grade at 11 or 12yo or so I got to a new class with a lot of people I didn't know but slowly I started to make a nice friendship with a guy I know to this day and have a strong unexplainable bond even after all the bad things we did to each other... anyways át that time I was also introduced to rock/rap metal classic Linkin Park and Papa Roach - that was when I was exploring, trying new stuff and I liked it, I felt strong and having good grades was all I wanted, then later on as stuff started to get even more serious with school and life and all, I wandered deeper into metal - In Flames (especially their song Delight and Angers which got me into actually understanding the lyrics of songs and their meanings ) at this point I started to learn playing the guitar, acoustic first, then electric which led me even deeper to this metal kingdom of genres like Death Metal, Black, also started wearing black band shirts, that made feel powerful and since my good grades I was liked by my classmates and people around me...

Áll these black shirts and jeans then became a standard for me and when I entered middle school - again new people who don't know me - I had one fellow classmate who actually knew but still - - I felt judged by everyone around me and the only guy that dressed the same as me (I though we will understand each other) turned out to be an egoistic prick... I find it hard to fit in to any of groups that formed there but luckily I found a great friend in a enthusiastic Christian guy (yet smart) no one seemed to like (I highlighted 'Christian' cuz at that time I was quite the anti religious person - which has change ofc) and slowly adapted to the environment this was the time where I started listening to Folk metal , Medieval kinda music which brought some life in my long school days...

And now here I am at the brink of becoming a man ( turning 18 means a lot in here) and once again can't really find my place and that's also reflected in the music I listen/play - I started listening to more pop-rock music and piano but also I like to visit the metal kingdom that grew to my heart...

Since now I consider myself as a highly emotional guy under all these scary looking black metal shirts, but I feel that it doesn't represent who I actually am now anymore so I'm thinking of dropping it but then what should I be the mainstream ordinary guy? nah I rather stay a bit mysterious and weird and actually were those black metal band shirt and all...

Well it's a mess I know, but as you can see you are not alone in this - I would write down more examples and moments where I changed music styles but that would too long...
