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

This week's roundup includes a rising British girl group bringing back that soulful '90s R&B sound, an electro cover of an '80s freestyle classic, Sweden's premiere EDM duo, and the surprise return of a U.K. disco diva. Check it out!

1.) Boris Dlugosch featuring Ròisín Murphy, "Look Around You"

More than a decade since their last collaboration together (2001's "Never Enough"), German House producer Boris Dlugosch and alt-disco goddess Ròisín Murphy have reunited once again to craft a new tune for the dance floor. "Look Around You," the twosome's sultry new disco groove, relies on a funky disco bass line, warm electronic vibrations, and of course, Murphy's velvet-smooth crooning. It's a warm, seductive slice of Studio 54-throwback goodness skyrocketed straight into the 21st century. Lock the doors, lower the blinds... you know how this goes.

2.) Disclosure featuring Eliza Doolittle, "You & Me"

British brother act Disclosure have already served up one of the year's best cuts so far after teaming up with fellow up-and-coming dance duo AlunaGeorge on their throbbing masterpiece "White Noise." Now, after signing with Cherrytree Records in the U.S., the group's putting out a four-track EP of singles, including their latest release: "You & Me" featuring British singer Eliza Doolittle. The tripping number sees Doolittle evoking Katy B, echoing above U.K. garage beats and early '90s house sound. "So please don't let go/ 'Cause you know exactly what we found," she urges. Fear not, Eliza: No one's going to be forgetting this song anytime soon.

3.) M.O, "Ain't Got Time"

In keeping with the steadily growing trend of mixing early '90s R&B influences into pop music (see also: Jessie Ware and Solange), rising British girl group M.O are giving us all shades of TLC, En Vogue, and SWV with their latest single "Ain't Got Time." The rising trio, which features former Mini Viva songstress Frankee Connolly, provide a breath of fresh air from the the dance-cluttered airwaves with their smooth moves, melodic vocals, and throwback appeal. "I ain't got time to care about people that don't care about me," they croon above a stomping drum beat. Preach, girls. Preach.

4.) Rebecca & Fiona, "Union"

Rebecca & Fiona know how to serve up some emotional EDM, and "Union" -- the Swedish DJ duo's latest cut from their upcoming follow-up to 2011's I Love You, Man! -- is the latest and greatest example. "We used to own this town/ share our hearts for better," the girls proclaim above a steadily building synthesizers, and there it is: a crashing beat breakdown of epic proportions! Rebecca & Fiona always know just how to strike the balance between emotionality and danceability. Grab your tissues and dance the night away!

5.) Parralox featuring Ryan Adamés, "Silent Morning"

Aussie electro-pop outfit Parralox must have dug deep into the disco 12" crates on Record Store Day, because the duo has just unearthed Noel's 1987 freestyle Hot 100 hit "Silent Morning" and given it a thoroughly modern reworking. Enlisting L.A.-based Ryan Adamés on vocals, the track alternates between the electro-rock crooner and Parralox's Amii Jackson. The bouncy beats are one euphoric throwback to the days where Heart, Kim Wilde, and Belinda Carlisle ruled the radio airwaves. Go ahead, add it to the "Totally '80s!" party playlist you've been preparing.
