Well, because Cleaning Out The Closet itself came out in 1999, and I knew that DLPM wasn't on the FII demos, so it couldn't have been from that album. And I've never heard the band talk about it, the way they talked about ACOS or To Live Forever, so nothing indicated that it was written as far back as those two. And since I didn't have the actual copy of Cleaning Out The Closet, I didn't have the label to tell me when the song was written. So that was the best guess I could come up with.
