It doesn't matter where the knob is or what hand you turn it with. The paradigm Tony (ynot) mentioned is simply the natural interface. Using a dial for volume isn't a fair comparison. There is no UP or DOWN scrolling in volume. There's loudness and that's just something relative. With something visual, you want the default behaviour to match other intuitive procedures. Movement to the right (clockwise) is equivalent of progressing forward. Forward in the list is down. So that means rotating clockwise moves the list up the screen. Just like the Hijack menu.

But, I think it would be horrible to have the Player's menu system be vertical. I much prefer the player's menus to Hijack. MUCH. Vertical playlist browsing is something completely different however - and I suggested or wrshed for a vertical ability a long while back (esp. since it already exists in searching and Now&Next displays).
