Motown Sounds Philly style instrumental \"Bad Mouthin\" was an underground hit on dance floors in New York, London and Chicago from the late 70's onwards. It was also famously sampled in Bob Sinclar's no 1 \"Gym Tonic\". The original is a pretty dense, everything in all the way through style production, whereas the JN mix opens things up in a bit with more room for the individual parts to be heard. The end result is an extremely energetic bassline driven disco cut that works super well on the dancefloor.
