Are you singing all the time??

Hey, a few days ago I read someone here saying they sing to themselves to regulate and I've never thought it could be related to autism cuz I sing ALL THE TIME. I sing while showering, while cooking, while cleaning, whenever I'm alone and when I'm out I sing to myself really low, even just sing in my head, I mean this is happening like 85% of the time, I can also have the same song stuck in my head for WEEKS.

Now that I think about it, it really helps me keep myself together or like ground (?) (idk the right term here), and can also work like a replacement for hands stimming.

Just wanted to know if this happens to someone else.
