Even the parts that get more clubbish fit the lyrics well, and the hip-hop-oriented x-over is ill. That bass is a nicely placed element, IMO. There's a few points where some higher-end countermelodies/counterpoint don't do so well for me, esp. near the end; it starts sounding a bit much like 70s progressive rock timbrally, which I think is very, very easy to overdo. It's not wildly out or anything, just not really the direction I myself would have taken it.
