Songs won't stay unchecked
I have a fairly large library with quite a bit of music that I don't want to keep on my phone. I have checked "sync only checked songs". My problem is that quite a bit of the music I uncheck in the main library will turn up checked again later. I've unchecked again, synced, to find the music gone, great. Next time I go to sync, the music is checked again and it gets back on the phone again. What am I missing??
