So here’s the story. I have a 128gb iPhone 6S Plus. This enables me to store a selection of my photos, 4K video and games.
It also allows me to hold around 30gb of my music on the device.
So last night I decided to chill out and listen to a few tunes and at the same time test a few bespoke music apps.
These third party apps were showing that I only had 9 songs installed. WTF. Where had 4,000 songs disappeared to?
So by connecting my iPhone to iTunes, it starting to automatically add again the songs that had just vanished.
If anyone knows why this happened here then please leave a reply in the comments.
