Daryl, sorry I'm late to the party here. This was great! Your wife is an awesome singer and this is a catchy song that's gonna stick in my head all night now. LOL!
A few little mix things? Nothing bad, I promise. :) The song is so killer, I think it can benefit from having a stronger kick drum with a little more thump force to enhance the dance groove the song has. What you have is good...but I'm talking about one of those kicks you use to really rattle some glass. I think this would kill with a kick like that. Subjective of course, but that's what I'm feeling...but again, what you have is fine. I've been working a lot on this genre with some pretty big dudes....and one of the things that always has to be there (especially when you have a hook as good as this) is a "thumper" rattling the walls. :)
Lead vocal was really nicely eq'd. You could probably get a little more low mids going on though just to thicken her up a little bit. That's one thing with female voices....I find that if I don't use the right low mids, they just don't quite have enough impact. They always drive me crazy because I don't want them to be too piercing, yet I don't want them to be too warm and bottomy. You gave a really good balance of everything in this though...great candidate for a mastering engineer to do his/her magic. Very well done brother, I thoroughly enjoyed this.
