To me, TFK have always been a band who makes ALBUMS, not songs. I mean, sure, yes they make songs, they have tracks on their albums, but the experience of the album is so much greater taken as a whole rather than as songs. This doesn't mean they don't have great SONGS, although usually those happen to be their epics like "Stardust We Are", "The Truth Will Set You Free" or "Love Is The Only Answer". But they have some songs that stick out, particularly ones from Paradox Hotel, which was a more song-based album anyway.
TFK's albums are just better taken as wholes, and even though nearly half of their albums are double-CD length, they're still amazing taken as a whole. Like what you guys said, I doubt I could name songs and tracks off many of their albums, but they haven't made an album I truly disliked. Sure, there are some like The Rainmaker or Adam & Eve that I didn't really get INTO, but there's still some great moments on those albums (both, oddly, are single albums).
They're a different beast than, say, Spock's Beard, who write albums full of songs, where you can listen to them out of context from the album, but more or less, with TFK, there's just something better about the songs when listened to in context of the whole album. I don't know what it is, but they're like a REALLY good deli sandwich - with all the right ingredients, as good as some of them may be individually, they're SO MUCH TASTIER when taken all together in ONE BITE. And when you FINISH that sandwich, it is just SO satisfying, especially the double albums (which, I guess if we're talking subs, they'd be the foot-longs).
Bands like Dream Theater or Spock's Beard or Marillion make albums full of songs that aren't (typically) needed to be heard all in one go, and I like that about THOSE bands. They're more like chips, in regards to lunch foods, albeit different flavors of chips. But you know what you're usually getting each time you get a new bag of chips, and as a whole, the bag is great! You may get one or two chips that aren't as good as the rest, but you know they're all good, just more or less the same across the board.
Then we get a band like Transatlantic, which, just happens to be a full meal of sandwich AND chips, and you just can't help but want more even though you're stuffed by the end of it.
