I have not mentioned it to him. We are not exactly friends anymore so I wanted to get info first.
He has yet to copyright the song, bit I do believe that he's in the process of it.
I did write some of the arrangements of the production, though, and we collaborated on the rest. I don't know if that matters. So should I be involved in the copyrighting? I don't necessarily want to. Like I said, I don't want any money. I just want to be able to show samples of the sound quality and production arrangements on my website.
