With almost 5,000 songs in my database, there are some that get left out. So I made this SPL:
Last Played is not in the last 12 months
Genre is not Books & Spoken
Genre is not Comedy
Genre is not Audiobooks
This grabs all the songs I have never played as well as all the songs I haven't played in over a year... which is 823 songs. I don't have enough time to keep on top of this! Too much data has become a bad thing.
