Six weeks and hundreds of frustrated guesses later, ZM's $50,000 Secret Sound competition has been won by a new mum with an 8-week-old baby.
Aimee Balle was the station's last caller for the day and had nearly given up trying to get through when she correctly guessed the secret sound was a car ashtray opening.
"I thought I'd give up and not call. But I thought I'd press the call button one more time," Balle said after winning.
