It's Tuesday! Time for another round of "5 Must-Hear Pop Songs of the Week!"

This week's roundup features a bangin' remix of one of Brit Brit's most personal tracks to date, some Swede-pop lusciousness, and your new favorite anthem for taking a #selfie.

1.) Britney Spears, "Tik Tik Boom (WAWA Remix)" featuring T.I.

While the Holy Spearit -- aka Britney Spears -- has been busy cracking the whip in Vegas, she's also been weighing her options for single No. 3 off of Britney Jean. Fans have been teased with everything from "Alien" to "It Should Be Easy" to "Now That I Found You," but B just keeps us wanting moah.

The latest potential contender? Her urban club-banga "Tik Tik Boom" featuring T.I., which got a suite of bangin' official remixes over the weekend.

Polish duo WAWA's interpretation might be the most fun of the bunch. The mix gives the track a scorching EDM makeover, wrapping Brit Brit's vocals around pumping House beats. It's not too slow, not too quick -- just enough to make you tik tik boom.

2.) Freeform Five, "Leviathan" featuring Róisín Murphy

Disco goddess Róisín Murphy has been fairly quiet for a few years now, spending time with her family and enjoying her personal life. But every now and then, she comes out of nowhere with an almighty dance-floor anthem, usually in the shape of a one-off collaboration.

And she's done it again: The Irish crooner's teamed up with London-based electronica troupe Freeform Five for a massive collabo called "Leviathan," which ought to make a serious splash on the dance floor. (GET IT? LEVIATHAN? SEA MONSTER?!)

The gentle throbber is less about mythological monsters and more about getting your life in order, as Róisín delivers some solid life advice: "Do it yourself, and if you get it wrong at least you know it," she suggests. You can dance... For inspiration.

3.) The Chainsmokers, "#selfie"

In our glorious digital age, the #selfie reigns supreme: Enter The Chainsmokers, the NYC-based DJ/production duo with their eyes and ears firmly planted on Instagram. Inspired by a growing generation of proud #selfie takers, the two have crafted what is almost destined to become a viral smash.

The track layers the most hysterically asinine commentary by a club queen on top of thumping EDM beats, including incredible quotes like, "I only got ten likes in the last five minutes. Do you think I should take it down?" and "That girl is such a fake model. She definitely bought all of her Instagram followers!"

Appropriately, the accompanying video -- shot in a club, duh! -- features #selfie cameos from the likes of everyone from Snoop Dogg to David Hasselhoff. Grab your phone, and head to the dance floor. #LuvsIt

4.) Marlene, "Stay Awake"

By now, we should all know that when you're prowl for pop perfection, simply head to Sweden for the goods.

Marlene is a relatively new Swede-pop crooner who dropped her brilliantly shimmering debut single, "Bon Voyage," last year. Now, she's back with a dreamy new number, in which she wants to do anything but dream.

"Kiss me like the morning light, let me stay awake forever," she urges above a twinkling piano and big, booming hip-hop beats. It's a slinky, sultry electro bedroom ballad dedicated to an all-night kind of love affair. Just try and squeeze in a few hours of sleep, yeah?

5.) Indiana, "Solo Dancing"

File this one under "One To Watch," stat. Indiana is a brand new artist out of Nottingham, England, and she's got a dark disco throbber for your listening pleasure.

"Solo Dancing" is a chilly li'l dance-floor thumper that sees the songstress crooning moodily underneath the flashing strobe lights and smoke machines. "I go dancing so intense, I will dance till the bitter end/ No point asking 'cause I always dance alone," she sensuously speak-sings above a steady synth pulse.

You know the girl dancing on her own that Robyn was singing about? Yeah, it's totally Indiana.
