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

This week's roundup includes a teaser track from a Buzzworthy-approved pop princess in the making, some sweet Swedish heartbreak on the dance floor, disco vibrations, a lights-out hit, and a brand-new banga you'd have to be Kat DeLusional to ignore.

Tinashe, Kat DeLuna, and more in 5 Must-Hear Pop Songs of the Week!

1.) Tinashe, "Stargazing"

It's safe to say that things are going well for Tinashe, one of Buzzworthy's more recent buzzed-about acts. After releasing her debut mixtape In Case We Die earlier in 2012, the up-and-coming R&B-pop princess cut two videos for EP tracks "This Feeling" and "Boss." Oh, right: And she recently inked a record contract with RCA Records. Not too shabby, eh? But before she starts cooking up her major-label debut, the 19-year-old songstress is already prepping the release of her second mixtape, Reverie.

"Stargazing" is the first (free!) taste from the collection, a hypnotic slow-burn of chilly vocals, somber hip-hop patterns, and twinkling electronica. "I'm still wishing on a star/ hoping you will feel me wherever you are," she coos above the song's dreamy soundscape. It's a silky smooth, endlessly repeat-friendly number, tailor made for a night of staring off into the stars. Appropriate, given that Tinashe's career is likely to shoot off into the stratosphere within months.

2.) Kat DeLuna, "Wanna See U Dance"

Sound the alarm: It's Party O'Clock! Kat DeLuna, born Kat DeLegenda in the Dominican Republic, lives in a fanciful, make-believe world where dancing is the currency of life -- and trust, she's loaded. To kick off her upcoming album, ViVa Out Loud, the pint-sized dance floor princess returns with "Wanna See U Dance (La La La)." The central thesis of the song is fairly complex: Kat DeLuna wants you to dance. Actually, that's about it. Set atop RedOne-esque synthesizers and a seductive Latin groove, Kat's latest killer cut stands proudly beside the rest of her fiery hot classics, including "Push Push" and "Drop It Low." Now drop it down to the floor!

3.) Don Diablo featuring Angela Hunte, "Lights Out Hit"

Rapidly rising Dutch DJ Don Diablo has been churning out remixes and original tunes for years -- and now, he's got a "Lights Out Hit." Part of his first EP with Columbia Records (the Lights Out EP), Diablo's sizzling new track features vocals by Angela Hunte, the same singer-songwriter who helped to pen "Empire State of Mind" for Alicia Keys and "Do Somethin'" for Britney Spears. The bangin' club monster comes blazing out the speakers with a searing, synthesized beat and an anthem-ready declaration on repeat: "It's a light out hit!" Frankly, we'd be hard pressed to disagree.

4.) Agnes, "One Last Time (Orion Remix)"

Several weeks ago, rising Swedish producer Orion released his debut single "In The End," which I loved to bits and pieces back in June's 5 Must-Hear Pop Songs. Now he's back for another round of dazzling disco pop, this time in the capable hands (or rather, voice) of Swede-pop goddess Agnes and her latest single, "One Last Time." Filled with lush synthesizer patterns and soaring strings, Orion's remix highlights the original's agonizing heartbreak, while it simultaneously invokes the spirit of Robyn. That's right: More heartbreak at the disco. Strut, sniffle, repeat!

5.) Luca C & Brigante featuring Róisín Murphy, "Flash Of Light"

After unleashing her grand masterpiece Overpowered in 2007, Róisín Murphy has been popping up all over the place, contributing vocals on random disco tunes and tidbits over the past few years. The latest, "Flash of Light," sees the Irish disco queen collaborating with Italian duo Luca C & Brigante. "The sands of time are running high/ Take me down, I don't want to live with an ordinary sky," Murphy cries out above the sulky, forlorn synthesizer throbs and playful xylophone riffs. It's a gorgeous, hidden disco gem, as only Murphy could provide.
