The song was written by Mike Stock, Matt Aitken, and Steve Crosby and was produced by the former two.

A music video made for the song features the four band members searching for pieces of their logo.

[1] Music Week referred to "More Than I Needed to Know" as a "bright and breezy pop tune".

[2] Can't Stop the Pop named the song as Scooch's best single, calling it "killer", describing it as "dancefloor heartbreak", and noting the contrast of the song's wistful lyrics with its upbeat production, but criticised the international cover artwork, calling it a "Photoshop disaster".

[4][5] The track spent nine weeks on the UK chart and is Scooch's highest-charting single and only top-10 hit in their home country alongside their 2007 Eurovision entry, "Flying the Flag (For You)".
