I have to review for my math exam a decent amount. English is sort of hit or miss, and then Ill have to study a good amount for chemistry. I hate chemistry.
So I listened to "bring me back to life" by evanescence and there is certainly a similarity between that singer's voice and the female singer in your song. They both have a "soft" sort of voice? I dont know how to describe it to be honest.
And both of you have a music connection, and have worked together, so conversation shouldn't be too big of an issue. You should go somewhere and "test the waters" so to speak. It sounds like you two would be a good fit, but then again, what do I know about relationships lol
