help me find this annoying noise

When driving, I always hear what I can only describe as a quarter vibrating against a piece of metal. It's a humming/vibrating sound. It sounds like it is coming right from the center console, or passenger seatbelt area, where you click it in. I always try grabbing/pushing on stuff to see if it stops, but it never does. It also only does this when I give the engine throttle, it does not do it at idle. Not too big of a deal as I always have the radio on, its just frustrating that I cannot find it

My 13 access cab sings to me everywhere I go

 

you should hear my truck in the winter

 

Is it an access cab? There is a recall out for the upper seatbelt mount which can apparently come loose. Otherwise I think you have a rogue quarter on the loose.
