Belt squealing

So my serpentine belt has started squealing really badly lately, I have changed my tensioner, my idler, and my belt and I have a new water pump waiting to go in but now I'm not even sure if that's what is causing it. I can't stand the sound and its friggin driving me crazy, any ideas on whats causing the noise?

YouTube - Belt squeal
Heres a video so that you can actually hear the noise. It is also much worse when I am moving.

Loosen the pulley that is all the way down on the right, then there's a very long bolt (about a foot long) behind it that tightens the belt. After you get it where you want it, re-tighten the pulley.

Can tighten the V8's belt .

I know you have a new belt , but , it sounds like my old belt to be honest . I'd try squirting some WD diectly to the belt , takes just a little . If the noise goes away , you got a bad belt . If not , maybe it's from the AC compressor .

Observe the engine cooling fan and make sure the w/pump bearing isn't wobbling the fan . My buddy is fixing that issue as we type , lol .

I used to only buy the Goodyear Gatorback Belts but nobody locally carries them anymore. So now I just buy the most expensive belt out of all the cheap ones that they carry.

I think I used a prestone on the 5.9 and a gatorback on the 5.2 . No issues since

If you want the gatorback , rockauto.com has them , what's few more days right .

Dayco's been around for a while , can't see it being too bad a product , Autozone carries them . Unless someone can say something bad about them ?

Sorry to bring this back from the dead but after another new belt after the dayco started squealing I put a gatorback on and the squeal has still come back! It seems a new belt temporarily stops the noises, but not for long. Any other ideas on this because it's driving me crazy.
