I don't know what you mean by "passive." If you mean ambient-ish, then certainly not, at least not compared to Vol. 8. If you mean in quality density....then not really, either. There's enough REALLY good tracks to make a decently sized album on par in terms of size and quality with Vol 6 and 7.
IMO Vol 9 is the best Homestuck album. It's got a lot of awesome tracks and the filler is at least decent for the most part.
