I personally think (and this is just an opinion) that if you're going to go for a synthesized voice you might was well go full fledged and go with the DAFT PUNK or Autotune sound. I think it will give your song more presence and make it more commercially viable. I think the songs are very very good and have a nice glide but the artificial voice throws it off because it's too obvious and almost doesn't sound intended. :-) I hope that doesn't sound too crazy.
