Nashville singer-songwriter Erin Nicole begins her solo project worrying about her own behaviour in a relationship that is going well. Following her work with Aleeda Blu, “Ruin This” makes an uncomfortable introduction: happiness has arrived, and she is already concerned about what she might do to it. A good partner has become one more person she could disappoint, which is a fairly miserable trick for the brain to play.

The single sits comfortably at the commercial end of Americana, drawing on pop and soft rock with a little country colouring. Its radio friendliness is pronounced, and I would file it closer to accessible adult pop than anything especially rustic. The musical setting is familiar enough that the personality of the singer has to do a substantial amount of the work. Nicole is easily the strongest reason to choose this song from a playlist full of similarly polished material.

Her vocal occasionally softens towards a half-exhale, and those moments are beautiful. Some of the firmness leaves her tone, with the breath becoming part of what holds the attention. The delivery is sensitive, emotionally involved and particularly appealing in these gentler passages. She makes the anxiety of the subject sound intimate enough to interrupt the easy listening.

I enjoy the sensual quality of the voice, too, which gives the performance an affectionate undertow: the relationship sounds worth wanting, even as the prospect of damaging it occupies her thoughts.

The request in the song’s name also places a substantial responsibility in the other person’s hands. Being asked to help protect a relationship from somebody’s own impulses is an awkward assignment, however lovingly the request arrives. My sympathy sits alongside a little discomfort with that burden, and the combination makes the song more engaging.

Nicole’s concern with deserving happiness becomes more interesting when another person’s happiness is involved as well. For all its approachable pop manners, this debut concerns a situation that can get messy quickly. Her tender delivery makes the plea easy to care about while leaving its implications available to argue over.
