Here is a quick tutorial on how to make a sound similar to the "Sexy Bitch" dance lead. It uses harmonic 7ths which are also used in the classic Korg M1 organ sound. Make note of the sub oscillator.
OSC1: Juno Saw (or regular saw)
Coarse Pitch: 0
Sub Oscillator: -1 octave, level 127
Coarse Pitch: +19 (this is a whole octave and a 7th above)
Sub Oscillator: OFF
FX: Limiter 4:1 ratio, hard attack, high threshold
Guitar Amp Lead Distortion, Bass Guitar Speaker.
Reverb: Light reverb or chorus if desired.
This is only part of the sound. You could use noise in the attack if you have a third oscillator. You could also use another sub bass harmonic to be more like the original dance lead.
You can use this formula and play with it some more to get the sound you want. The reason this works in the mix is because the pitch difference of OSC1 and OSC2 allows space for other instruments or vocals in between.
