I was a little curious to see some statistics of the most performed DT songs ever, I got this from setlist.fm (don't know the accuracy of it though):

I was surprised to see 'Lie' in the Top 10, I didn't know it's been played THAT much? And I&W is very over-represented apparently
I've seen them in concert twice (2009 and 2014) and haven't got one single song from that album. What are the odds?
Regarding the I&W songs, keep in mind that the entire album was played at almost every show for nearly 300 shows in 1992 and 1993 and 2017. Those three years account for more than half of the plays of most of those songs (PMU being the obvious, biggest exception).
Not sure about Lie, except that it was part of the mini-set of Awake songs that got played for the 20th anniversary in 2014.
As for the odds of not seeing any I&W songs at two shows, to quote Beverly Hofstadter, "Is that a rhetorical point or would you like to do the math?"
Looking at those statistics, I'm more interested in the least played songs. Repentance was performed once, Disappear twice, You not me three times. That's kind of cool.
I wouldn't mind seeing YNM, but I hope the other two remain where they are.
I think this is going to be a controversial opinion, but this wouldn't be the first time that a fanbase adopted a band members opinion because "reasons". I maintain to this day that "Tai Shan" is slagged by the Rush fanbase because Geddy slagged it, not because it's actually a bad song. I think some of the opinions of Space Dye Vest are rooted in the fact that it was - to a degree - marginalized. I think several of the opinions surrounding Falling Into Infinity (and certain songs on that record, you know who you are) are shaped by reactions to the band regarding third party inputs, or outright contributions.
Tai Shan was slagged LONG before Geddy ever made his "error" comment (which I believe was in a 2009 interview). I definitely agree that MP's comments about SDV and FII (particularly the latter) have colored fans' opinions - both for the negative and in terms of positively influencing some fans' opinions about the FII reject songs. That said, as the recent countdown showed, SDV is well-liked (at least in this forum).
