Originally released in February 2017, the series has grown to five volumes, with most containing mashups, exclusive mixes, and unreleased music as well as various DJs and producers introducing themselves during interludes. The fourth iteration, Now That’s What I Call Riddim Vol. 4, contains around 110 songs from a large number of artists. A fifth installment was released in January 2020. Kardon marked it as the last in the mix series and included songs by Skrillex, Excision, Doctor P and Boogie T.
