This also happened to me.
The problem is: many times somebody already has uploaded a discography which now is dead, then it is not shown in a superficial search. To certify if a stuff already exists, you must make a advanced search and choice the option "Active with Dead" in the field "Type". Even if your discography is more complete, it will don't be accepted. In your case I guess you can try to upload each album in a separated torrent.
The moderators are really very stern, but this is good, because it keeps the site organized.
Personally, I think the torrents that are dead must be deleted when somebody wants to upload the same stuff or better. I cant't understand why not.
