I don't know about singing. I'm not a singinger type singer. My metal influence has led me to the side of strictly growling and I've only ever practiced singing in the event that I need to let an actual accomplished singer know what I'm getting at. But I really like to write lyrics. I'm willing to do that much, but between my lack of capability and my lack of quality recording, I think it'd be best for your song to stop at lyrics... on my part anyway.
