No, you should not submit to another category. If the editor thinks it's worth listing at all (which, as I say, is not obvious -- you might want to think about your "about us" page from that standpoint) then it'll be moved to a better category (if there is one).
The phrase "official fan site", oxymoron though it seems, is fairly common and usually means the webmaster is an officious and pompous idiot. BUT -- I hasten to add -- I remember than there is an author who HAS actually "approved" a "fan site" which has even more material than her publisher's site (even though it's an exceptionally web-oriented publisher!) So if you claim to be official, back that up with some kind of evidence (to avoid looking like the usual such claimants).
I still don't know if the site is listable at all. After all, press releases by definition aren't so _very_ unique. And (however outdated) the official official site is and has a unique authority: only the company itself can authoritatively proclaim who it is and what it'll do for money. A fan site, no matter how officiously material is connected, is (when repeating official material) merely one of many other second-hand sources.
Press releases by definition: not unique, no matter how many or how fresh. Affiliate links to buy recordings are also by definition not unique.Promotional material, no matter how original with you, simply isn't content: it's just another form of advertising we skip past looking for the real content.
For an ODP editor to recommend the site, there needs to be content with unique information or unique authority. For a site that looks like just-another-affiliate-link-farm-with-rehashed-promotional-material, you're going to need to make an effort to show uniqueness. After all, amazon.com has all the releases for all those national companies, and a good many more beside. And how many CD purchasers do you know who actually buy material based on the COMPANY that issues it?
Well anyway: that's the kind of thinking that'll drive the editorial decision. If you have unique content, you can be thinking of ways to feature it, to serve the kind of surfer the ODP is designed for. If you don't, you can, I suppose, abandon hope.
But a multitude of submittals cannot make up for an absence of content. And, as I mentioned, we're asking very specific questions about the content. If that's not the kind of content you're interested in providing ... that's OK, the ODP is not for you but it's a big internet.
