NowPlaying tab scrollbar elements obsolete?

[hiccup]

In an effort to try and keep the Sample Skin updated and correct:

Am I correct in thinking these elements are obsolete and can safely be removed?

"Content[NowPlaying].ScrollBar"
"Content[NowPlaying].ScrollBar.Lowlight"
"Content[NowPlaying].ScrollBarThumb"

I tried a lot of layouts, but they never seem to overrule or apply in any situation.

(which is not a problem, since the auto-colouring seems to work very well in all cases)

no longer used.
Also i have removed: Content[NowPlaying].Body.Default
