Hi Kelvin,

The Disco sound I know was coming from the BeeGees. Well... I heard more, but their sound I liked. Even the high falcet vocals then.
The AI ladies do a very nice singing (you did a very good job on that), but like Ron said, there is something missing in the song.
I think all the instruments are 'too thin' in volume and in body, the drums included. So the girls swim in thin air and weren't glued in the mix (if I may say it like this).
From the start of that electric piano, I got that old fashioned 'midi-sound' feeling. Maybe you could experiment with more bass, reverb and delay in the song?
And listen to Brain. Make it stereo...

All the best,
Hans
