Music smart playlist

Good mornig.

My currently use of music menù is:

Music

Kodi show all my artist in data base. I click on one artist and the program show all album of him in my database. I click on album and the program show all songs in it.

Today I’ve created a smart playlist for the O.S.T. CDs.
Working fine.

Now my goal is this:

Music

Kodi show all my artist in data base. I click on one artist and the program show all album of him in my database (except O.S.T.). I click on album and the program show all songs in it.

With smart playlist there aren’t successful…

Il possible?

P.S. O.S.T. is genre= original sound track
