"Even more so than the celebrated Chemical Brothers — who began recording after Prodigy but received a hits compilation before — Liam Howlett and Co. were fantastic singles artists who also fashioned excellent full-lengths. As such, Their Law 1990-2005, the singles collection that could put the cap on their career, is a collection that will leave listeners breathless but also one that can't capture how special Prodigy were to the electronica and rave scenes." AllMusic, 4.5/5 stars

Their Law: The Singles 1990- 2005 was originally released in 2005. The album features tracks from the four XL albums: Experience, Music For the Jilted Generation, Fat Of The Land and Always Outnumbered Never Outgunned. Pitchfork gave the album a 9.1 upon its release, and in their review of the album, Entertainment Weekly said that it "is here to remind us that the British electronic band stamped out some of the most brutally powerful dance music of the '90s."
