Between her smashing of La Gaga’s single-digital-sales record (“Tik Tok” sold 610,000 to “Just Dance”‘s 419,000) and the fact that she seems poised to unseat Susan Boyle on next week’s Billboard album charts with her debut Animal, it’s a very good week to be Ke$ha.

But can the Jack-swilling, Diddy-feeling pop-rap minx replicate her number-one magic five times over, as Gaga has? Let’s look at the evidence, shall we?

Gaga: Bona-fide crazyballs fashion explosion

Ke$ha: Still in the minor leagues, but trying. Sort of

Gaga: Can actually sing the crap out of her stuff live, belying AutoTune stereotypes

Ke$ha: Hmm. Questionable

Gaga: Garners gossipy sexuality-related headlines

Ke$ha: Ditto.

Gaga: Immensely Google-able (77 million-plus results!)

Bottom line, Ke$ha has yet to prove whether she has the mysterious je ne sais quoi that separates the one- (or two) hit wonder from the global superstar. And she seems more fight-for-your-right-to-get-sloppy Beastie Girl than the kind who will likely ever bestow a power ballad like “Speechless” on us.

There is, of course, room for more than one blond provocateur with a Bowie fixation in pop music. But you tell us, Music Mixers, which one will history remember most? Or will both be forgotten by 2012, when only John Cusack lives to tell the tale?
