The song was originally going to contain a sample from Double 99's RIP Groove, however due to clearance issues, the sample was removed to prevent delays in the release of the album. When the sample was cleared for use, Mic Check was announced as a single. There are three versions of the song; the album version, the radio edit, which is exactly the same as the album version but with the sample reinstated, and a remix which contains the sample and is a heavier, dancier version of the song.
Following strong radio airplay throughout March and April 2010, "Mic Check" debuted on the UK Dance Chart at #14, before climbing to #13 the following week. Upon release, the single climbed a further 5 places to its current peak of #8.
