Play counts in Albums and track layout

[66Sixer]

When I choose play count in the albums and track layout, it does not show the total play count for the album.  I'm not really sure what it is showing me.  As you can see from my screenshots, this particular album has four plays when viewed as "tracks".  When viewed as "Albums and tracks", it shows one.  I'd like to actually see the play count for the album.  Can I create my own custom field for this?  If so, how?

create virtual tag with formula "$Sum(<Play Count>,<Album>)".

Thanks for the help boroda.  I initially entered the formula with one extra space and it didn't work, but I figured out my error and it works!  You are awesome!!!
