I'm a big fan of notebooks. I write poetry, doodle, etc. But every once in a while I'll write something that sticks. More often than not though, if I write something of merit, it happens all at once. My favorite songs that I've written just happen. Here is an old favorite called Bone White Skin Tight that you've inspired me to post. I wrote it in less than 10 minutes. It just poured out of me. Felt really cathartic too.
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?
