Okay, bear with me here.
I usually have some sort of song on my mind. It isn't the same as getting a song stuck in my head.
I can usually think of a song I had listened to for a few hours, days, weeks, or months, and some cases, even years. I'll hear some of the lyrics, notes of music, and it sounds like that particular song. Sometimes, I can even choose a song that I want to "listen to", as long as I've heard it before.
Do neurotypical people do this, or no?
