LTTA is definitely the highlight of Cparts for me. I've heard that song used as a backdrop on several TV shows and sporting events.
I have to say, however, that Cparts was pretty disappointing for me. I had the album 2 months before it was released (some random dude on Prodigy online sent me a copy cassette), and to this day it was just kind of blah. I really love the sound and engineering of the album, but the songs are just blah. When i read Neil saying that Animate was one of their all-time bests recently, i nearly gagged on my Cinnamon Toast Crunch.
That being said, I love LTTA, Cut to the Chase, Double Agent. And NH and AS are good. The rest.... yuck. I can't believe they still play Stick it Out... that could take my vote for worst Rush song ever. And i'm not alone - they did a poll at Rushisaband.com during the tour and an overwhelming 65% of people singled out that song to be the first to remove from the setlist.
OK, i'm done complaining. Weak Rush is still great.
