Note: Only albums (LPs) are covered in this discography. Unfortunately singles aren't included here due to lack of information on my part. I know of many singles, but haven't been able to gather a complete list. Also with only have a handful of images and no track listings or release dates I don't have enough to start a singles area. If you know of a source that details every EP ever released by date, I'll consider adding it. But if you're looking for a certain song, generally, all of the songs released as singles can also be found on several of the albums within.
It should go without saying, but non-official releases aren't included here. Only canon. So if you're wondering why your "Best Singles Collection" CD you picked up at the local comic shop for $5 isn't listed here, it's probably because it's a grey market item.
