Content:  AllMusic editor Jose F. Promis noted that the song "took a phrase popularized by Arsenio Hall and made it into another cleverly infectious Top Ten smash." Billboard wrote, "After forging a guitar-driven pop/hiphop sound that is being heavily copied by others, groove clique deftly sidesteps into James Brown-style funk territory. Rapper Freedom Williams tells amusing tales amid retro-horns and percussion." Penelope Layland from The Canberra Times stated that it is "the best track on the album", "with its clever, catchy lyrics and smooth beat." Dave Sholin from the Gavin Report commented that writers/producers Cole and Clivillés "have successfully crossbred a unique brand of rap and melody that's taken them on back-to-back trips into the Top Ten. This third entry maintains their infectious rhythm, strengthened by a title that will keep audiences hummmmin'." Australian music channel Max included "Things That Make You Go Hmmm..." in their list of "1000 Greatest Songs of All Time" in 2013. A reviewer from Music & Media wrote that "the secret behind the success of these dance/pop providers is the good hook in their songs. This time it's the saxophone part, which is repeated after each line."
