I really like the feel of the song as well. It has a smooth and mellow approach. What you have is a very good foundation to add onto! I do think once you add more it will become much better of course. One idea would be to speed it up and put a 4-on-the-floor beat on top. It could be an interesting trance song! Just an idea. I thought I had heard that beat somewhere! If you want to check out some of my music and tell me what you think ( the song "painted" in particular) go to:

BTW, sorry for not replying to your Sp808 and Jp8000 question, I really don't know what to tell you? You might want to check out the Sp808 forum( if you're not a regular there already?)
