MrC, Robert mentions that the view is not available when he goes there, and to be honest, I'd be very surprised if it were!!
Robert, the theory behind MC's saved views is great, the practice however, is way, way too restrictive. I've made several detailed posts about this, but not kept the links, I'll try and find them later. A potted version of the details can be found in the tutorial I pointed you to a while ago...
Saved Views: Right at the start of this exercise, there was the "View Picker" with its little thumbnails and descriptions of predefined views that could be loaded with a double click. The theory here is that if you hit "Load view" that same view picker opens and you would pick a saved view to load. In practice, most often the view you want isn't there because it does not match the media types of the location you want to add it to. Similarly, the "Save view" option is fraught with issues. For example, there is a browse button in the save dialogue, but, if you save the view anywhere other than the default location offered, it will not be presented as a "Load view" option, ever, and there is no way to browse for a saved view from the "Load View" tool. Views are saved as jvi files, but these are not associated with Media Center, and when forced, Media Center does not know what to do with saved view files when opening them from the hard drive. In my experience, best practice is to forego these two altogether and rely on library backups to preserve the view layout, and when you want to have a view copied, just drag and drop it where you want it in tree, and when you drop, you will get a "Move / Copy?" option. Minor tweaking after copying is a breeze compared to fighting with the "Save / Load" views options.
You can force things along manually using a text editor if you want it badly enough though...
A jvi file saved from an 'audio only, playlist view' has a "view info type" value of "3" and a "Media Types" value of "1".
These values can be found in the first few lines of the file:
<JVI version="1.1">
<Item Name="View Info Type">3</Item>
<Item Name="Media Types">1</Item>
<Item Name="Name">Playlist test</Item>
If you edit a saved view jvi file in a text editor (notepad will do) so that these values are reflected, that view will then be presented in the "Load View" tool, but will no longer be available in audio viewschemes as a view to load. (edit a copy perhaps?)
It got me thinking though...
Playlists and smartlists are essentially just that, lists of files, no panes involved, so, I'm guessing you are after the column layout you have in your audio view to be duplicated in your playlist view?
If you right click on a list column header, you will see "Presets" in the menu, and from there, you can save the column layout. If you then go to your playlist, you can use the same menu to load that saved preset.
I am making the assumption that when you say "Playlist library" you mean the "playlists" area of the same library as the audio view you have saved, rather than a completely separate library in its own right.
There's a couple of things to mess with for now anyway... let us know how you get on...
