Items showing in the "On My iPhone" tab when my iPhone is connected as a circle with an exclamation mark in it.

Hi timroberts1979,

When tracks in iTunes display a it means the file cannot be located; it may have been moved or deleted. For this issue, we will need to refer to the following article:

Alternatively, if your media was downloaded from the iTunes Store, you may be able to download it again free of charge:

Thanks,
