Autistic people are often attracted to one particular line in a song and will sing that one line aloud or in their brain for days, possibly in the singer’s accent. This may be considered a form of stimming, as well as a form of echolalia.
@AutisticAdam@actuallyautistic I think I also do that with particular parts of songs that I can't stand too. I never knew why. I can't explain it as anything other than stimming, but I didn't know that until just recently.
