How to prevent playlist songs from adding to my local library?

[Bakartridge]

Hope I can explain this in a way that makes sense, but I have playlists made up of songs that aren't in my local library (as in, the local library is albums I have saved, but the playlist contains individual songs I have saved), but if I listen to a song then it's added to my library, sometimes creating duplicate entries if a playlist song is from an album I actually do have saved in my library, how do I prevent it from doing that? Otherwise there's a bunch of 1 song albums added to my library, just manually removing them causes them to come back when I play the song again from the playlist.

See if this works (it should from what I understand):
Go into Wacup Preferences -> Media Library -> Local Library -> Options tab and make sure Automatically add played item to the database is not checked. 

Hopefully that helps.

That worked, thanks!
