I would agree on PMU and TSCO. I love both still, but PMU was a huge grower and didn't stand out to me for a while just because of how awesome I&W is. TSCO is really good as well, but also suffers from being one of the weakest songs on an incredible album. Of the handful of times I've seen DT live, TSCO was also the only song where I didn't hesitate to take my bathroom break.
Personally, I'd say Space-Dye Vest and The Looking Glass. The first I feel somewhat kills Awake's momentum and ending, coming off of Scarred's fade-out and such, and it features my least favorite KM lyrics. It's a moody, mellow song and a good song, just too angsty for me and a bit less involving than their other ballads. The latter isn't as much a fan-favorite as others listed. It's divisive, but those who like it seem to really like it. Unfortunately, it's one of the few DT songs I will always skip, I just find it boring and the things I like I can find in other songs phrased similarly but much better. Too many Rushisms and the solo is too reminiscent of ToT without being as good.
