Back' and 'Music Sounds Better with You', if you will." Stylus Magazine's Dom Passantino rated the single 8/10, describing the song as "handbag house's last hurrah, except we'd stopped drinking Hooch by then and it was all about sambucca..." Tom Ewing of Freaky Trigger rated the single 9 out of 10, saying: "There's a beautiful tension in 'Groovejet', an apt flirtation between Bextor’s languid, cut-glass vocals and the delightful indulgence of Spiller's music. It’s not just any disco he's reviving, after all. No Chic for Spiller, none of that poise or aspirational elegance. The sounds 'Groovejet' loots are the syn-drums and ray-gun synths of disco's overripe peak and decline, when it was corny, wonderful, mass-market pop music: you can hear hints of Kelly Marie or Amii Stewart in the song, before that sweetness falls back into the dreamy groove. 'Groovejet' is a fond tour of disco when it ruled the world, and proof that it still could." He described the music's sophistication as coming from Ellis-Bextor, who "offsets the track's bubbly repetition, adds a bittersweet note without ever sounding like she's above it. In fact she sounds carried along by it." The song was ranked at number 486 in Pitchfork Media's list of the Top 500 Tracks of the 2000s.
