Questionable Tendency's Menagerie of M........

So recently I've become a tad obsessed with the Scissor Sisters. Especially Filthy/Gorgeous since I've adopted it as my new theme tune.

The thing is, I've been checking them out online and it appears that they're not particularly well known in the US. I was just wondering if any of my American friends could verify this and if anyone could explain this utter TRAVESTY.
