From reading this I'd guess that it isn't hard for you to compare at all, SiT wins hands down, all the time!While reunion albums are very good, I can compile a list of 'cons' for every album and each song from it. There are exclusions, like The Man Of Sorrows, Out Of The Shadows, maybe The Wicker Man too.
Somewhere In Time has no flaws as an album and just one song has a flaw of bad lyrics. It's hard to compare.
So you would have those 3 as your Top 3 Reunion tracks? Fair play, interesting choices
