Each Friday, Pop Shop will showcase a handful of tracks that have been burning up its speakers over the past week. These can include a brand-new song or a track that's been simmering for a minute; the only rule is that it's worth space in the Pop Shop!

LITTLE BIG TOWN
"Your Side of the Bed" (3:42)
Capitol

Little Big Town's compelling new ballad boasts all the ingredients of a country classic: married members Karen Fairchild and Jimi Westbrook trade lead vocals and deliver performances that capture the loneliness and angst of a couple wrestling with the growing distance in their relationship. The cut sizzles with emotional tension, and when Kimberly Schlapman and Phillip Sweet chime in with stellar harmonies, the song reaches another level. -DEBORAH EVANS PRICE

ARIANNA FEATURING PITBULL
"Sexy People (The Fiat Song)" (3:29)
RCA

Italian singer Arianna didn't just recruit Pitbull for her brand-powered new single -- she also brought in Charlie Sheen, Shaggy and a slew of professional athletes for its video. "Sexy People" flaunts a punchy beat, and although Arianna's impressive voice isn't given enough room to operate, she now has our attention. - JASON LIPSHUTZ

THE TRANSPLANTS
"Come Around" (2:45)
Epitaph Records

Tim Armstrong, Rob Aston and Travis Barker's recently reunited punk trio opts for lighter, twangier fare on "Come Around," a single to emerge from the first Transplants album in nearly a decade. Aston drops a rare vocal turn, but it's the shout-along, roadside-bar chorus that should stick with ­listeners. -DAN HYMAN

AXWELL
"Center of the Universe" (5:25)
Ultra Music

Fresh off a final tour with Swedish House Mafia, Axwell returns to the solo game with "Center of the Universe." The 35-year-old's latest cut is a tension-releasing summer epic, primed for remixing by DJs across the globe. Most important, however, the producer isn't looking back on past successes: "We're made of stardust/Our life's ahead of us," goes a choice lyric. Don't call it a comeback. - DAN HYMAN

BETTY WHO
"You're In Love" (3:55)
Self-released

One month after Billboard premiered her brilliant debut EP "The Movement," Betty Who has moved on to her second single from the four-song release. "You're In Love" carries an equally sunny disposition to its predecessor, "Somebody Loves You," but with even sharper lyrics: "Don't try and tell me you don't want to see/What it would be like to grow old with me," Who sings before widening her arms and tackling the chorus. - JASON LIPSHUTZ
