Just an idea, when one knows that a band had a demo or whatever in 1997 but knows nothing about it (no tracks or anything) maybe instead of listing it in the additional notes it could be listen in the bands discography, except not as a link. So among all the links to known releases the unknown recording could be listed in normal print. What do you think?

Sounds like a good idea to me. Maybe the text accompanied by something like "information not available" in brackets. It'd certainly keep the pages less cluttered as whenever a band has some or all of it's discography in the additional notes it looks pretty bad.

Nah, keep it in the additional notes. It works just fine the way it is.

I agree that it's not broken the way that it currently is. Even if it were, however, it's worth noting that at this point in time one is not likely to see any major formatting changes (protocol may be a different matter) in the current iteration of the site. Any such modifications or overhauls are more apt to be seen in a future version.
