The Octavarium album as a whole. I just don't like the weird sound effects that connect the tracks, and some of the songs feel underwhelming to me (TALW, IWBY and NE). The track order doesn't help too much, either. Some fans rank this album in their top 5 DT albums, and I just don't see why. At least we got TW and the title track, which are two of my favorites from the catalog.
