Oh yeah. When everything has me all freaked out, I turn on the music and sing, sing, sing! If things are just noisy and I'm with my kids in the house, I'll just bust out singing to release the tension. They love it and usually join in, lol
Also, for my daughter, she DEFINITELY stim-sings. Sometimes it's just a loud humming that gets louder the more overstimulated she is, sometimes it's repetitive short verses from a song "twinkle twinkle little star, twinkle twinkle little star," etc.
