Well imo The Human Equation, Into The Electric Castle and both Universal Migrator albums are his best albums, and 01011001 hasn't ever really grabbed my attention, never even checked out the best of, soooo I'm 5 years behind in Ayreon terms, but I'm definitely going to check this one out. I'd be interested to see what he's done with the long songs. I love his recurring themes in songs, and those should be more obvious within the same song.
Looking forward, and not going to listen to snippets. I always like his albums as a whole, let alone songs, no 40 second snippet of any song of him is going to give me goosebumps, I think.
