Weird rattaling sound coming form the windshield?!?

[YarisSedan]

Okay i have this sound thats been driving me nuts. Sounds almost like someone has a tin can with some beans in it rattling it around inside the car. first i thought it was the loose change inside my little compartment by the left. Then i thought it was from the dash. Started pressing holding and banging on everything while i was driving tryign to see if the sound would change and go away. Then really listening it sounds almost like its up top. I push against the windshield and it goes away!

Has anyone had this issue. I am guessing maybe piece of glass is broken around the molding and dropped somewhere and is rattling around or something. I cant figure it out. Might have to take it to the dealer and see if its something they might warrenty or possible have a tsb for.
