Always a difficult situation. The music production was well done to my ears. I agree that the musical style and the lyrics do not compliment each other. It sounds as though she must have done the vocals to the track that you produced, so I'm wondering why she didn't like it at the time.

The vocals are back and weak in the mix for sure, but her vocal styling does not fit well with this type of track. It calls for a singer who can really belt it out in my opinion. Not being a musician herself, I can understand why she thinks a weak performance can be turned into gold. Hey look at Taylor Swift.....LOL

Not getting paid is the worst part of the whole deal.
