I think the whole FAS debate hits at my larger, more comprehensive controversial opinion.
First, my controverisal theory, which is the premise behind my controversial opinion: Ever since the band started self-producing, they've been under the impression that every song they record during a given album session deserves to be on that album.
Now, for the opinion: This has lead overall to less consistently good albums, and more albums with throwaway tracks. For something like "False Awakening Suite", I guess it's cool on the live intro tape, but did we really need it on an album that (I think) is already too long? Does it add value to the album? Would it have been better rolled out live, and then maybe released on a live album? My opinion is"No, No, Yes", respectively, but it doesn't matter - DT wrote FAS while they were recording DT12, so of course, they're going to include it.
DT just doesn't seem to believe that any of their songs should be left on the cutting room floor. To me, that's frustrating, but I totally respect and understand that some fans love DT's approach. For better or worse, they pile it all on the plate every single time, and while I'd prefer shorter and more concise albums, I can see why other fans love that DT put everything on the table.
