Hi Manjor and thank you for your reply. All the music in my music library and on my iPod has been bought and downloaded from iTunes. And just to say that I did delete a couple of recently bought songs and re-download them to see if that would resolve the problem. Unfortunately, it hasn’t so I don’t think that deleting my whole collection and re-downloading will make any difference in this case.
I’m convinced that the issue relates to the latest software update on my iPod as there were no problems prior to me downloading it. I did speak to an Apple advisor yesterday but they weren’t able to help me and suggested that I enquire on the forum instead. I’m disappointed because my iPod is less than 2 years old, and if I hadn’t updated with the 15.7.5 update it would have worked perfectly as before.
Best wishes and take care.
