2. How do I add a category to my Artists view to show me different categories of Albums that I define?
If you're using the normal Artists view, that shows album thumbnails, there are several ways to do this. I'll outline one way that can work.
A. Copy your artists view to a new view by dragging it to the top where it says "Audio" and choosing "Copy". Now you'll have "Artists (1)" that you can edit, rename, and experiment with.
B. Let's create a new library field to hold your new Album Category information.
1. Tools > Options > Library & Folders > Manage Library fields
2. Add new field. Fill out a name that makes sense. I used "Album Category". Make it Data type: String and Edit Type: List .
3. Click Ok until you get out of all of that.
C. Edit your new view (Artists (1)). Right click, then select customize view.
D. In the "show categories in this order" box at the left, remove everything except Album Artist (auto).
E. Add a new category by pressing Add.
F. In the dialog that pops up, select Expression. Then cut and paste this expression into the big field that says "expression to group by":
FirstNotEmpty([Album Category],[Album])
G. Click OK on everything until you're back to the main MC screen.
Now this view should show you Artists as the top level and when you drill into a particular artist, it will show you either the Album Category, OR the Albums as the next level.
You need to tell MC what Album Category you want to use for some of your Elvis albums. Select an album (or several albums). Then open the tagging window with Edit > Tag . In the new tagging window click the gear icon and select to show all fields. Now go find the [Album Category] field. Type in what you want to use for Category. For example: Live, or Studio, or Bootleg . Click anywhere to save that change, then close the tagging window.
Now your new view should show your new Album Category under Elvis. You can repeat this process to tag all of your Elvis albums. You can now apply this same logic to other albums by other artists, and you'll get categories there too.
Typing this up it seems like a LOT of steps. But it's really not too bad. I did a proof of concept on this in about 3 minutes.
Good luck!
Brian.
