Uh, yes, I figured that out later!

The problem was that there's an unwanted playlist called "on-the-go" that I can't get rid of, and that's the one that comes up first if you scroll backwards. It was only later that I realised that "Wolfstone" and "Wagner: Parsifal" were what I got to if I went back beyond that.
Does all pop music come in little bite-sized chunks with no relationship to each other? Why is the iPod so aggressively designed to take tracks out of context and mix them up with each other? It seems to make it as difficult as possible for the user to keep longer pieces of music together. What about musicals? It's not just operas and symphonies and oratorios that get split into tracks that make no sense out of context.
When I turn the thing on, every time I'm forced to listen to the same random chunk of "Parsifal" while I navigate the unintuitive menus, simply because the first word sung in the track is "Aber" (it's obviously alphabetical). It seems to have no care at all that many people will want to listen to music in integrated packages that are more than a track long.
It's completely bizarre.
