I can't say that was the same for me. I fell in love with Dream Theater from the get go. Systematic Chaos was the first album I bought from them. The Dark Eternal Night, though the vocals were ran through audio filters a bit too much, I think it was still a very solid track. However, I just can't get over how wickedly-haunting Metropolis p2: Scenes From a MEmory was. Track-to-track, it was a wonderful listen.

As for Learning to Live, I'll have to go back and listen to it because I don't remember the song [i]that well[/i]. As far as the best Dream Theater song. For me, I would place my bets on These Walls. I don't know if you feel similarly, but I personally go back and listen to that song as much as I possibly can. It's not only one of my favorite songs off of the Octavarium album, but I would place it in my top five Dream Theater songs. Honestly, that entire album has a lot of great songs. Probably my favorite DT album thus far. Of course, I haven't been able to grab their latest effort, so I may feel differently after I do.
