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…
I’ve always had background music in my head. It only stopped for a while when I was on vyvanse 70mg…which was way too strong for me. Now that I’m on a 30mg generic med the music came back. Sometimes I can change it but it usually stays playing a couple songs randomly…
