Oh, and since I got two IMs a couple minutes apart from people as they found this topic, the answer to "how did I come up with this?" is actually pretty simple.
I've seen a bunch of rank 100's, and I always get disappointed when I think about songs I might have considered nominating, but I either go nahh, or "aww, I only get 5," or whatever. This was a chance for me to put up an entire list...and then the results get to be the product of more than one person's opinions. Plus, it's an interesting reversal on the normal rank 100 formula.
I have no idea how this will work out in the long run, but the goal ultimately will be to make a number of passes through the entire list. I'm hoping like 5 or 6. We'll see. The songs on the first pass are just alpha by title, but they'll get rotated in the second, and then I'll probably sort them by performance from there or something.
