Songs disappearing from my library

Hi Katana San, unfortunately no help there, just off the top of my head I noticed The Waterboys “the whole of the moon” is missing from my library because I’ve heard it a million times letting my songs shuffle, now it’s vanished. Before that was Big County, the entire The Crossing album that I’ve bought in every incarnation since vinyl, was gone and I went and bought a second time in the Apple store before I considered this would be a recurring problem. I won’t know how many more are missing until I realize I haven’t heard them in a while. Would appreciate anyones input

1. Hi Katana San, unfortunately this doesn't help; I cancelled my apple music subscription because I pretty much already bought everything I want to hear, so the prompt to turn on sync library doesn't apply ("Turn on Sync Library. If you don't subscribe to Apple Music or iTunes Match, you won’t see an option to turn on Sync Library") & as mentioned earlier, I don't need a computer for anything so my own is ancient & hasn't updated itunes in years. I just use my phone & am now noticing more & more songs that have just vanished. Please help

Hi Picas, the problem is on my iPhone, which hasn’t been connected to my pc in years, do you have a link for that scenario? None of the ones posted cover that
