Nyx was just singing through the lyrics as well, just seeing if they fit the vibe that she had been envisioning as well. The beat she enjoyed, it definitely gave it that more haunting feel. And thankfully Angel knew her vocal range so there was a beautiful blend of low and high. But there were some of the lyrics that she was adding her own edits too, making sure that it was pretty obvious that she had changed some of them. Changing them to words that seemed better while she was singing. But this was apart of working together - giving input on what the other worked on. That was the only way that they could truly make something beautiful together.
