"Girl U Want" was allegedly inspired by the song "My Sharona" by The Knack, although Devo bassist and co-writer Gerald Casale has denied this claim. The lyrics, in typical Devo style, describe a relationship marked by unrequited love/lust for a woman. "Girl U Want" was first performed in December 1979 in a similar arrangement to the album version.

In the music video, Devo performs for a group of young women in the style of a performance from The Ed Sullivan Show, with two robotic backup dancers, one male and one female. Further implying the televised nature of the performance, the color in the video is deliberately altered to make the red of the band's energy dome headgear look almost purple. The band wears the silver naugahyde suits from the cover of Freedom of Choice, and mime the song with Moog Liberation synthesizers.

During the video, the camera focuses on the girls in the audience exaggeratedly enjoying the performance, including one girl who is visually implied to "wet" herself, which transitions to a scene of General Boy controlling the backup dancers. At one point, Mark Mothersbaugh pulls aside the curtain behind the band to show an overweight man on a vibrating exercise machine, attempting to drink a milkshake to the ecstatic reaction of the audience. As the video ends, girls in the audience are shown holding signs with icons, including an electrical outlet.

Steve Huey of AllMusic spoke of the song in a review of the album, stating "Several tunes – like the oft-covered "Girl U Want" – have a geeky (but pragmatic) romantic angst that was new to Devo albums, although the band's view of relationships is occasionally colored by their cultural themes of competition and domination." Huey also highlighted "Girl U Want" as an album standout by labeling it an AMG Pick Track.

Greg Prato of AllMusic reviewed the song itself, stating "While writing material for their third full-length album, Devo's main songwriters, Mark Mothersbaugh and Gerald Casale, took notice of the Knack's current success with their quirky single "My Sharona," and decided to write their version of the song. The result was one of their finest tracks, "Girl U Want"; but, strangely, it wasn't that track that made the album such a commercial success. The stiff yet irresistible main synth riff (doubled with guitar) is instantly catchy and memorable, while the lyrics deal with unrequited love. While some find it hard to look past Devo's wacky costumes and focus on their music, the fact is that Mothersbaugh and Casale were great songwriters. "Girl U Want" is definitely one of the most overlooked gems to surface from the early-'80s new wave movement."
