I would go crazy trying to do one of those. Not sure what criteria I would use. If I were strictly going by what albums I think are "best" and that I like the most, it would be a boring list because there would be a TON of Dream Theater, Neal Morse, and Transatlantic dominating too many spots. But then there are older albums that are hard to fit in where I feel like they are influential, and I loved them awhile back, but they haven't stood the test of time with me and I don't like them much anymore. And then there are also some where I wouldn't normally consider them as good as anything else in my top 50, but just feel like a top 50 list doesn't feel right without including something by certain bands. So, yeah, I have no idea how I would go about that either.
