Who doesn't like a little friendly competition between fanbases now and again? That's right: It's time once again for March Madness.

Like last year, we've nominated pop's most dedicated fanbases, thrown 'em all into a bracket competition and then called upon fans to decide which base, ultimately, will triumph. And yes, the competition is going to be fierce.

In this round, a battle between two massively talented and hugely popular girl groups: Little Mix and Girls' Generation. And there's a very good reason to go hard for each of them in this battle.

After dropping their latest album Get Weird, Little Mix recently just tore up the stage at the 2016 BRIT Awards with a killer tribal rendition of their hit "Black Magic." Girls' Generation, on the other hand, dropped their latest album Lion Heart last summer and embarked on their hugely successful Girls' Generation's Phantasia Tour all the way up until the New Year.

But here's the question: Which fanbase will move on to the next round — the Mixers or the Sones? It's your turn to decide. Place your vote below. This round will end on March 9 at 11:59 PM ET.
