I wondered about that as well! I suspect it might have been different songs or movements from the opera, but it didn't specify on the ABC site so I thought it would be a fun Easter egg to include. Glad you found it!

I wonder if that was supposed to be the Goldberg Variations (currently listed as unranked in 2001). That’s what Wikipedia has, but I don’t see a good source for it.

		Ooh nice pickup, might have to track down the original playlists on Archive.org and see if I can verify if it was indeed Goldberg. I did think it was odd that Goldberg didn't show up in 2001.
