I've often seen Music 1 libraries that have only the one, original 'view' of Categories. Okay, if that's what you want. But you can make up to ten different views, each displaying the songs with different data columns. One view I have shows Title, Artist, Tempo and Gender. Another view shows me "Playlist This List" (how many times the songs have been scheduled from within their current category) and "Total Plays" (how many times they've played since they were first added to the library). We can switch from one data-view to another with a mouse-click. Here's video showing how to edit the view templates.
