1. The 'preload images' intro screen would be a little obnoxious if I were still on a dial-up connection. Is it really necessary?
2. Overall, the layout isn't bad - the top navbar and side navbar work well together; the color choices are minimalist, and help to keep the user's focus on the content (images, jukebox, copy) instead of the site's framework itself. Nice.
3. The 'follow me wherever I go on the screen' javascript menu has got to go. In fact, these menus should be banned, just on general principle. This kind of menu always manages to obscure some section of content that I'm trying to view - additionally, the particular JS menu you've chosen doesn't work well in my browser of choice, Mozilla Firebird. Stick your menu at the top and side of your page and be done with it. Also, you don't need the same menu at the top, and at the side - pick one or the other, or put different choices in each location. Duplication is unnecessary here.
4. The 'Random Thought' at the top is easy to gloss over; you should consider changing the background color or text color slightly to draw attention to it (think: light blue background, for instance).
5. Some kind of Welcome message on the side - perhaps at the top of the main content, perhaps somewhere off to the side, perhaps following a link that says 'about this site' - would help to give users a clue as to what your site is for.
6. OK - I found your 'about' page in the 'navigate this site'. Rule #1 whenever you include music on your site: Don't have it 'auto-play', ever. If I were viewing this site at work, now my boss knows I'm surfing, and I'll never visit this site again. Or, if I happened to be listening to a CD on my PC at the time, now I have to listen to your music over Jon Scofield, and nobody messes w/ Sco. Keep the 'music player' bar at the top, sure, but let the user decide if they want to listen to the stuff or not. Besides that, the music that *is* playing is just awful.
There is probably more, but thats a good start.
