Virgin Radio Secret Sound! 2nd Sound REVEALED

Congratulations Crystal!
She guessed our 2nd Virgin Radio Secret Sound, it was the sound of a can opening! 
We’ll play a new Secret Sound at 7:40, if you can tell us what it is, you’ll win the $200 jackpot. 
If no one guesses, we add $105 to the Jackpot and keep guessing!
We play the Virgin Radio Secret Sound every weekday at 7:40, 11:40, and 4:40. 
Good Luck!
