I Agree, My Step Son Jordan is 17 this year and is Special Needs. He don't walk, talk, feed or change himself. I am his Main Caregiver, besides his Mom. I find that when he get agitated or ready to have a seizer. I play Country, Classic Rock or even Reggie/Hawaiian music and it just calms him down, Quickly.
