As documented in the Discovery liner notes, the song features a sample of "I Love You More" by George Duke. The sample was worked into an electronic pop song about unspoken love with lyrics by DJ Sneak and vocals performed by Daft Punk. Friend and occasional collaborator Chilly Gonzales remarked upon the unresolved chord progression derived from the sample, noting that the suspended harmonies contribute to the song's sense of longing and desire.
The track is known for the solo featured prominently on its second half. Thomas Bangalter revealed that the solo was created using a mixture of elements, aided by music sequencers. "No one plays solos in their songs anymore, but we wanted to include some on the album."Guy-Manuel de Homem-Christo also noted the duo's use of in-studio equipment to evoke the sound of a previous artist:
On 'Digital Love,' you get this Supertramp vibe on the bridge. We didn't sample Supertramp, but we had the original Wurlitzer piano they used, so we thought it would be more fun to have the original instrument and mess around with it. We use mainly vintage synthesizers, like older electric pianos like the Rhodes, Wurlitzer, Clavinet. We didn't use the Clavinet on Discovery, but I usually use it in my studio.
The American band Hellogoodbye often uses the first two verses of "Digital Love" in place of the second verse of the song "Here (In Your Arms)" when performing live. A live version of the song, performed by Danish group Alphabeat is available as part of an iTunes Live EP.
The song was featured in a GAP television advertisement. It featured both members of Daft Punk wearing their robotic helmets and gloves as well as GAP denim shirts and jeans. They appeared dancing with Juliette Lewis. When asked about Daft Punk's dancing in the ad, Guy-Manuel de Homem-Christo stated "It looks really simple to do, but when you're on a step with the crew, it's really not, even though the choreographer was really nice." "Digital Love" was also used by Nokia for a commercial of the Nokia 5300, and several MTV programs Is It College Yet?, Pimp my Ride, Date My Mom and Next.
