Pretty much most of my life I thought everyone had this (as well as vivid imagination) but now I dont think its as common. Like I can cue up any song in my head and it plays through, all the instruments relatively separated etc. A similar thing happens for writing music, I can write song after song and rarely feel like I “dont have any ideas”.
Sometimes I wish that power could actually be utilized…
It’s funny, my memory for things like dates is non existent. I’m also pretty sure I have a neurological issue preventing me from recognizing people. But damn, my memory for audio i think is perfect. I can listen to a song once and remember every beat and every word for years. It’s an odd thing to have thrown all my skillpoints into.
