What order did you listen to their discography in?

I have been a fan for about two years, and I kind of listened to their work in an odd order, and I'm curious as to what order some of you guys discovered their music in.

1. Octavarium
2. Images and Words
3. Scenes From a Memory
4. D12
5. A Change of Seasons
6. Six Degrees
7. Train of Thought
8. A Dramatic Turn of Events
9. Black Clouds and Silver Linings
10. Systematic Chaos
11. The Astonishing
12. Falling into Infinity

I have not listened to WDADU, and there really wasn't a rhyme or reason as to why I listened to them in this particular order
