Well I just couldn't take it anymore. After searching and reading how some disconnect or cut wires I decided to go to the source. This fix isn't for everyone but I simply couldn't stand that chime when my keys were still in the ignition.
I took some dash pieces off to get to the cluster. Pulled the cluster and took the black back cover off of it. There was the speaker. I stuffed some pieces of cotton ***** in the speaker then covered it with duct tape. Put it all back together and problem solved. It is totally reversible, all factory wires are still intact. It is so quiet I had to hold my ear as close to the dash as possible to make sure it still functioned. One my get by with just putting tape over the speaker. Anyways, this was easy for me and I'm extremely happy with the result.
I used green tape over the speaker before I put the black cover back on, it is in the picture

 

Just picked up my 16' and I have to agree it's A LOT more annoying than my 05's chime!!!
Thanks for the tip, although I am waaaaayy to scared to remove anything,.....yet! We'll see how it goes.

 

Update: You cannot hear your blinker by doing this.

 

on the 15's you could turn off the seat belt chiming.

Deactivating and Activating the Belt-Minder Feature (Driver Only)
