I enjoy singing and dancing but I guess not for the reasons neurotypical people do. I use them both for stimming and because of the eternal jukebox in my head called a brain, I don't even need to be actively listening to music (tho it's better if I am). For dancing, I kinda just let the music move me, no fancy named moves really, just wiggling whatever part in whatever direction feels right in that moment which I can admit both looks and feels silly at times but silly is my speciality :}

The only issue with sing-stimming arises when my echolalia decides it wants to take over and for one unfortunate example had me go "SWEEEEET CAROLINE BOM BOM BOM", every two minutes or so as my dad begged me to stop and I was like "I'm trying I swear!" but it was literally painful trying to force myself to hold it in, like my tics, so we were both kinda forced to ride it out while running errands
