Hello @JOE_SODD, hey I might have a better way of getting you to your end goal for this one. What are we working towards with importing everything as a playlist? Let me know and I’ll see if I have a better suggestion! Regarding your playlist options, we have a good article here! Let me know if you have any questions about it.
Use focus.
Go to performers and select the ones you don’t want from the list, they will appear in green, tap each one and that will turn it red and that excludes them.
Once you’ve excluded all the performers. Click on a track in the main window then from the top left menu select all.
Then from the three dot menu at the top select add to playlist.
