I like SFaM and ADToE. Also happen to be my #1 and #2 favorite DT albums.
SFaM has a bit of everything. 1,2,3,5,6,10,11, and 12 minute songs. Plus, aside from Beyond This Life, nothing really feels like it drags on. Finally Free is long, but it is too varied and too incredible to feel "too long".
At the same time, the songs that are not too long still do not seem like they end too quickly. Strange Deja Vu and Fatal Tragedy have enough variation throughout to achieve this phenomenon.
I also like the lengths on ADToE. It is packed to the gills with songs in the 9ish to 12ish minute lengths. I really love DT's songs of this length.
Sure, Outcry's instrumental section is way too long. But I think the thread is just referring to the actual lengths, not the content of the songs.
And having an album composed of many songs in the 10ish minute area, and still managing to have 9 songs on the album, is just awesome.
I'd have to say my least favorite is BCaSL. Having so few songs of great length runs a very big risk. If you do not happen to like, say, 2 of the songs, that is almost half of the album. And I know of many people who do not like 2 or more songs on this particular album.
What is sad about BCaSL is that, to me, the music is there. It is the lyrics that rob this album of being in my top 5. I still love the album, but the lyrical content is either corny, or unrelatable to me.
