Anyway to query this?

[Sammy20]

I want to make a new view in the library that lists all songs that have yet to be added into any of the playlists.

I'm organising all my songs and putting them into category's, but I just know I've missed some while browsing through the library. So being able to make a query for this would be alot of help to me.

BTW, is there a help section for using the query thing in add new view?
