I also try to avoid spoilers as best I can. Hell, I haven't even been on the DT side of this forum in almost a year trying to avoid spoilers. Sometimes it's just unavoidable. Just being here, people talk about the setlists in other threads that have nothing to do with Dream Theater or even music! That's how I found out about ACOS this tour, and Space Dye Vest on the 2014 tour.
But Don't Look Past Me, as I've said, was spoiled because a BAND MEMBER posted about it on Facebook. Then I saw the same post again shared by THE BAND. Once I saw that, I just figured that they were promoting one of the songs they were playing on tour, and that I could expect it to be played. Especially considering that the song is a leftover from Images and Words, I figured that they were going to hold on to it. I was looking forward to hearing it. That's where my original disappointment came from.
Today, however, I feel better about not seeing it. I realized that no one in Europe got to see it, or anywhere except the 13 shows here in the US. Looking at other songs that have been played 20 times or less, I have been lucky enough to have seen: Vacant (twice), Innocence Faded, Light Fuse and Get Away, Raise The Knife, The Answer Lies Within, and Overture. At this point, I'm chalking it up to not being one of the lucky ones to see it.
Also, I'm VERY glad that I was able to see To Live Forever. It's one of my TOP Dream Theater songs, probably Top 10. And it's a much better song than Don't Look Past Me. And now that I see that they've potentially dropped that as well, I'm counting my blessings this Thanksgiving, haha.
