Still can't figure out this noise

I have a better recording of an annoying noise In my 2002 UL that I am having a lot of trouble diagnosing. It's the metallic clinking sound in the first 20 seconds of this video (ignore the keys/key ring jingling). I've had several techs look at it and shake their heads. Heat shields have been removed from the ypipe and it's not corroded. All service done. The noise happens when I'm coasting with my foot slightly on the throttle, but not enough to maintain speed, and is more prominent the faster I'm going. Losing my mind over this, can't believe I'm the only one...

I hear the keys rattling but if its that noise from the 7 - 12 second area, that's pretty loud and I'm surprised that it cant be pinpointed.
How's your A/C working (if it was on). I know that the A/C can make a sound similar to that when its low on freon. I had a noise like that on my wifes car that was pretty low on freon. It ended up being a leak so I replaced a couple of parts but the noise it was making was almost a hissing sound but also had a tinny sound. Hard to explain but it stopped when the A/C was recharged.
Good luck it your quest to find the culprit.

This noise isn't a/c related. It seems to be driveline or exhaust related, but likely driveline.

I have not found the source of this noise yet. I thought I had it solved a few months ago, I replaced the worn/broken engine mounts and for a short time the noise wasn't really there, then I noticed it coming back and now its getting louder, but still not as prominent as before. I also had the driveshaft center support bearing replaced, it was squealing badly, so we can rule that part out as the source. I can now hear this noise to some degree constantly and at all speeds, not just on the highway. Here is a clip of how it sounded before I had the engine mounts replaced:
Let me know if you find anything out.

i was hearing a different noise in your video. i have a noise similiar to your s coming behind the ac/vents. i heard thru my research it is possible the servo motors going bad. i got your note about the engine mounts etc.. i guess i mis heard the noise in your video. i was thinking about doing the engine mounts, i heard it helps with the ride being that it takes weight off the front end with new mounts, did you notice that the ride changed with them?
