Continuing with the DJ International catalog:

Music Is The Key

DJ International DJ 888
Written by Steve Hurley
Produced by J.M. Silk and Rocky Jones
Lead Vocals – Keith Nunnally
Mixed by J.M. Silk and Farley Jackmaster Funk

(Note: There is a 4th mix – the 2nd track on the A-side in the ‘Basement Key’, but my copy has a nasty scratch on it and I can’t get that track to play without skipping.)
(Useless trivia – the rap in this song was later used by Cat in the Prince song ‘Cindy C’ off the Black album. It’s not clear to me whether or not they used the rap with permission or if they just ripped it off.)
