It doesn't sound familiar to me. And that happens to me a lot. A tune just comes to me and it sounds to me like I must have heard it somewhere. I usually can never find out where I might have gotten it, though. I do remember one I figured out. That was many years ago, and I changed my tune enough so it was my own. Sometimes one of my tunes reminds me of another tune but, when I finally figure out which one, I realize it isn't actually the same, just has the same kind of feel.
