BLACKPINK are back, and they're on fire. Quite literally.

YG Entertainment's massively popular new four-piece girl group came crashing onto the Billboard World Charts over the summer with their 2-track debut Square One, featuring the massively infectious "Whistle" and "Boombayah." (Start learning each member's name now: there's Jisoo, Jennie, Rosé and Lisa.)

They're a big deal already: so much so, in fact, that BLACKPINK already surpassed long-running acts like Girls' Generation in a recent brand recognition ranking in South Korea, coming in at a shocking second place overall. (Not bad for debuting in the same year.)

Today in South Korea (Nov. 1), to keep the momentum going strong, the girls just dropped a follow-up called — wait for it — Square Two, featuring two Teddy Park-penned new tracks. And within just the few short hours they've been out, both videos have racked up nearly half a million views each.

While "Playing With Fire" packs the usual K-pop punch of high energy dancing, chicer-than-you fashion-forward styling and synth-filled production (and plenty flames, because playing with fire...duh), "Stay" is a stripped-back surprise, gliding along a simple guitar melody that showcases the girls' impressive individual talents as singers. Also, the music video is the stuff of muted color, melancholy fantasy Tumblr aesthetic dreams.

The group's versatility, no doubt, will only win them even more new fans.

Watch the videos for "Playing With Fire" and "Stay" below, but no rush — these girls definitely aren't going anywhere but further upward. Burn baby, burn!
