Fair enough, but if you take a full scope of their work, you can see the way in which they've used similar spectrums, similar types of sounds in order to make many of their tracks multiply interconnectable. For example: one of their first singles (not on any of the albums, but on the 10-year retrospective double-disc) was called "Dirty," which uses the same plaintive whine as on "Dirty Epic." If you have the "Born Slippy" CD single, it's actually two tracks: Born Slippy and Nuxx. On their live album Everything, Everything, Rez becomes Cowgirl becomes Rez again. The idea of telecommunications, wire connections, USB ports, etc being sexualized is a principal trope in their lyrics -- check Dirty Epic against Push Upstairs and Push Downstairs.

Sorry, I'm a bit of a fanatic.
