We are doing some tuning on the server. The host is telling me they want even more money per month, but I think we will be able make some tweaks. Basically the server memory is being exhausted and then it gets slow. I have a thread going over at Xenforo and they gave us some tips and it should work out better soon.
I don't think the Music section is working correctly. I submitted several Viennese waltz song months ago, which appear under "Latest Additions". But if you're trying to search by the Viennese waltz genre, they're not there. I've seen the same thing with music that others have submitted: the genre lists are not getting updated, only latest additions.
