  Passage: "Step in the Name of Love (Remix)" is the title of a hit song by R&B singer R. Kelly.  Taken from the 2003 album "Chocolate Factory", the song became the tenth single from Kelly (and the final one to date) to reach #1 on the R&B chart, particularly on the strength of the song's remix.  It also peaked at number nine on the pop charts on December 2, 2003.  The original "Step in the Name of Love", which is on the unreleased 2002 album "Loveland" as well as the Chocolate Factory album, described a dance style initially created in Chicago called "stepping".

In the UK, the song was a double A-side with "Thoia Thoing".
