I know this is beating a dead horse into the ground, but here is my particular problem.
I have done all of the fixes that have been recommended, yet when I am on my iPhone anytime I swipe the song to get the delete button the song starts playing.
The song is in my library, does not show on my device on iTunes, on my iPhones, Settings>General>Usage>Music shows No Data. However, on my iPhone, when I open the Music app, there are still 3 songs displayed.
I have tried to unclick Manual manage, sync, and reclick Manual manage sync. It never shows up in iTunes on my device and it is always on my iPhone.
Sorry for the repeat I kind of felt mine was slightly different. Thanks
