Every Good Boy Deserves Favour -> It's not a musical

It's a play, with background music composed by Andre Previn. At no point did anyone sing in this piece. Does this qualify to be in the database?

There are a number of straight play cast recordings in the database so i think this recording of incidental music is applicable.

I'm not against having play albums in here. But it would be nice if there's a tag somewhere saying it's a play.

That's an interesting idea, it would actually be helpful for very obscure recordings with no track lists to know if it's a musical or not.
