I'd say Octavarium, 6 Degrees and Learning to Live are given. I'd say it's going to be Voices and either Pull Me Under or Fatal Tragedy. However, I can't see any of those three missing the top 50, so your guess is as good as mine.
I'll also say I'm surprised we haven't seen As I Am yet, but I can't see that one in the top five, even though it features some of JP's best guitar work.
