Yup, you're right, that's "Soopher" in 050701. I haven't watched all those old movie clips yet. "Soopher" opened up the 2008-06-11 radio show.

I think it's a little erroneous for us to draw conclusions about song evolutions based on a few common elements. Obviously Soopher and Mo Move share a common opening, but beyond that, the structures and sounds of the songs are so different, I don't think they share any evolutionary path except for that common loop. Same thing for the drums in Mo Move and Beautiful Burnout. It's similar sounding, but not even the same rhythm, so I don't think there's any influence beyond Rick liking those drums.
