OK, here's a question related to opening songs: Do you prefer "Where the Sour Turns to Sweet" or "Calling All Stations"?
For me, it's the first one -- best song on FGTR IMO.
I almost didn't buy CAS because of the initial impression I had of the title track. It's one of those songs that took me a while to warm up to. (Once I heard the whole album I was glad I bought it, though.)
I like both, but CAS is better - it's a good, dramatic, emotional song. (But it's not in the same league as e.g. Behind the Lines, Watcher, TLLDOB.) My opinions are kind of the reverse of yours - for me CAS is one of the best songs on that album, and WTSTTS is one of the weaker songs on FGTR
