Because I’ve been humming it and playing it both in my head and on my iPod all weekend, here it is: Britney Spears’ new single, “Circus” (off the album of the very same name):

Catchy, I’d say. Primo use of the circus motif to double as a subtle-but-not-quite sadomasochistic atmosphere — “when I crack that whip” and all that. (With apologies to PETA, of course.)

Not that the three-minute regular version is enough for me: I’ve also indulged in a couple of remixes. The “3 Ring Circus” mix is pretty good, although I’m still looking/waiting for extended dance reinventions, at least eight minutes long.

And of course, you can’t load a remixed track onto your iTouch without whipping up accompanying album art. Might look like a lot of work, but really just a few minutes out of a (thankfully) long weekend.
