Finally finished, two weeks after school started. Sad to say, there is no Led Zeppelin at all, Jim. I asked my dad WTF, and he says, "oh yeah, well about ten years ago I went through and, anything that I also had on CD, I threw out. What's left is only what I had never replaced on CD, maybe a third of everything I ever owned."
And yes, by threw out, he means in the garbage.
Oh well.
