Technique to Remove Large Amount of Songs from a Playlist? (FIXED)

I must have accidentally added one of my playlist to another, probably by drag and drop. I've since created a smart playlist to identify the songs in both playlist. I want to remove these songs from the playlist that the songs were accidentally added to.

Is there a quick and efficient way this can be done? It's a few thousand songs.

*EDIT: Since I don't use the Love/Dislike feature, I was able to Love all the songs from my smart playlist, sort the playlist that the songs were accidentally added to by Love status, and delete those songs from the playlist.
