Absolutely. That stuff is MC's bread and butter. There's an indepth look at view customisation
here (v17) and
here (v13) that might be some use to you. Although old, much of v13 and all of v17 is still current today.
What you are looking for is the "Set rules for file display" area of the customise view tool. Here, you can set search rules to restrict the files shown in the view based on tags or file location.
It doesn't need to be complex... [groupings]="classical" entered here would restrict the view to just those files tagged with classical in the grouping tag...
It would then probably be better to rename the view so that it's better identified in the tree. Once you're happy, you could drag the view, drop it on "Audio" and choose the copy option you see when you drop, rename the copied view in the tree, and alter the search to one of the other five groupings.
Shout if you need more.
