We went twelve rounds over My Humps, except that time it was Devin defending it, but I'm more than happy to take this on. This might not make much sense, but here goes:
There's a difference between great pop music, and great pop songs. A great pop song is something you play at a party. Something that gets people dancing at a club, something that makes you feel like you've been dancing for days. I don't want to single you out, RD, but a while back you said "The Fear" was the greatest pop song you'd heard recently. I like that song a lot, but it doesn't want me to get up and dance. A great pop song can come from anywhere, and, as Ray said, you grade on a scale.
I did a lot of djaying this summer, and I played a lot of the songs we're talking about often. It was for teenagers, mostly -- the target audience of a lot of these songs. But Michael Jackson and ABBA got just as much a reaction from the crowd as a set of Lady Gaga songs or Cobra Starship or, surprisingly enough, "Love Drunk" by Boys Like Girls (which is another example of a song that is great in the moment but whose moment quickly passes).
Couple of months later, I was doing a wedding and both Lady Gaga and the Black Eyed Peas were requested, and the reaction was just as big from the thirtysomethings in the crowd as it was from the younger kids.
The right song hits you, you just want to dance. That, to me, is the hallmark of a great pop song. It remains to be seen whether "Poker Face" and "I Gotta Feelin" and "Human" will stand along the "Since U Been Gone" and "Hey Ya"s of this decade, or the "If I Can't Have Yous" and "Dancing Queens" and "Don't Stop Till You Get Enough"s of past eras. And so forth and so on.
Finally, I want to prelude this by saying that this is not me trying to be a name-dropper, but I know enough people who currently know or were friends with Stefanie/Lady Gaga at one point. From everything that I've heard, plus what I've read, it's an act - and a very intelligent one. She's basically taking our obsession with the Britneys and the Lindsays of the world and throwing it back in our faces; it's not so much that she's an attention whore so much as we are voyeurs for wanting to look in the first place.
And in the end, we cannot read, cannot read, her poker face. Her-her-her-her poker face.
