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

This week's roundup features a cut from a UK-bred dark-pop diva's glorious new record, our favorite Bajan bad gal, and a crushing power ballad from the Quebec's reigning crooner queen. Let's go!

1.) Celine Dion, "Loved Me Back To Life"

If there's anyone that can resuscitate the pop power ballad on radio these days, it's the "Power Of Love" singer herself: Queen Celine Dion. The iconic Canadian chanteuse has delivered time and time again (I'll allow a moment to gaze nostalgically into the distance as the "Titanic" theme plays in your head #NeverLetGo), and this year's no exception. For her first English studio album in six years, Celine's leading with "Loved Me Back To Life," a major power ballad penned by pop's most in-demand songwriter, Sia. It's a serious chills-inducing belter, packed full of emotion and crisp production. Welcome back, Celine, we missed you!

2.) Natalia Kills, "Trouble"

After months of controversy, that girl is still a goddamn problem: Cherrytree Records' resident H.B.I.C. Natalia Kills has finally unleashed Trouble, her moody, introspective sophomore effort that's packed with defiant anthems and devilishly good troublemaking. The album's title track, "Trouble," is the (tar-black) heart of the record, which sees the UK-born songstress making solemn declarations over '90's rock-pop and soldiering, Jeff Bhasker-produced drums. "Hold me down in the siren lights, love me even when the lies ain't right/ Light my fuse, I'm the dynamite," she declares. Screw good behavior -- this is the kind of trouble you'll be dying to get into.

3.) Tensnake featuring Fiora, "58 BPM"

Leave it to one of house music's most thrilling pioneers to come up with the summer's slinkiest surprise. "58 BPM," Tensnake's debut single after officially signing with Astralwerks, is a gorgeously chilly slow-burner that sees the producer teaming up with Berlin-based songstress, Fiora. Together, the two craft something truly lush. "We could do this fast or slow/ Take your time, and we'll both know," she tenderly croons above the ambient noise and slow-chugging drum machine, evoking just a touch of Prince in the process. Let's just call it what it is: A jam for some late-night freakin'.

4.) Rihanna "What Now (R3hab Remix)"

Oh, you thought the Unapologetic era was over? Think again! Rihanna's coming back with yet another offering from her moody 2012 opus. Following her summer semi-single "Right Now" (like, was that even officially a single? #Ph*ckYoReleaseDates!), the "Stay" superstar is taking a break from Instagram to launch "What Now," a soaring, introspective power ballad. Last week, a slew of major remixes  wound up on Beatport, including an offering by the reliably amazing R3hab, who confirmed the single's release on Twitter. It hasn't even been a full year since her last album, but we were already going through some severe #RihannaNavy withdrawal -- so thanks, Rih.

5.) Metals, "That Ain't Real Love"

Rising Melbourne outfit Metals is serving up a whole lot of sass with "That Ain't Real Love," a new release off of their upcoming debut EP. "You don't love me/ you love the way I make you feel about yourself/ and that ain't real love," soulful crooner/ frontwoman Candice Butler declares. Preach! The song's a major hodgepodge of sound -- there's some deep dub throbs and stinging electro, as well as over-driven rock guitars and a crashing drum finish. Genre-blurring ferocity? Very into.
