I know that feeling. The first poem of mine published was like that. Of course, that was just the first draft. Re-working it took some time. I liked your song. I don't think it necessarily matters what it means. Sometimes when people look at or listen to or take time to experience art they put way too much value on meaning. The other extreme happens frequently too, but I think for things to be successful as pieces of art they need to engage both the technical and the enjoyable.
I don't think it matters what a song means either. But this song, this song had a deep effect on me and those effects weren't immediately revealed. It took some time and I'm still figuring this one out. That's probably why I like it so much. Edit: I'd like to read some of your work. Is there a link to where someone could get a book of yours?
