I think last.fm's new beta phase is misrepresenting track reports. If you look at the top 50 tracks, Beyond the Red Mirror, Follow the Blind, and Battalions of Fear are all missing, except for "Valhalla", which is probably coming from live releases. This is obviously incorrect as Beyond the Red Mirror in its entirety was in the top 10 until just before the beta phase.
That said FTB is a solid album, but it's just a minuscule snapshot of a way they sounded for a few years. It doesn't really embody their aesthetic. If the charts were fixed I would say Valhalla would be at least in the top 5, and Banish From Sanctuary top 15, at least.
