My total guess/gut feeling is that glamazon on the two sites is the same person because the flailing style, use of caps, and M.O. of posting possible future developments like fact "I guarantee" are very similar (they were posting about a rumor of Adam performing at the Grammies and a stadium tour on the ALTR site and then vaguely saying they had gotten the info from Alisan Porter's blog and Adam's "forum"?).
I don't know whether they heard the single or not, but most everything (besides possibly the hung-up/sfw comparison) sounds like it could be wish-fulfillment trolling to me.
I just made up that name lol, for a troll that picks up on fan wishes/hopes/guesses plus any current industry berting on twitter and reflects it back to them. The comparison to the Rihanna song was something that a fan elsewhere had posted wishing that Adam's new song would sound like a few days ago for example.
This would be similar to the person on twitter who was describing seeing Adam and Sauli with Finnish friends being cute at a restaurant in LA but later turned out to almost certainly be a troll.
The funny thing is that this kind of 'trolling' isn't meant to necessarily trick people, but just to get the poster lots of positive attention and love for awhile, and in order to be believable what they describe is something that very much could be true and is in alignment with information coming from more legit sources.
For myself, the OTT-ness is making me back off because I don't want to have too high expectations for the song or how it is received by radio. I want to be very happily surprised, not slightly disappointed if it doesn't immediately take off like wildfire or sound like the best thing evar!!!111 if you know what I mean.
So far the most theoretically unbiased thing I've seen is from the Gaga inside knowledge dude, who supposedly also heard Kelly's MKIA single early. That he likes it and all the DJ's seem to be excited about it (even if this is part of Sony created buzz) is enough to have me pre-flailing like whoa.
ETA: also I think we'll probably know soon enough (before xmas even!) what is true and what isn't, so it doesn't really matter much to me either way at this point.
