songs on my iphone but not on itunes on my pc
I recently purchased a couple of songs from the iTunes store and when I was syncing them onto my iPhone (13 Mini) I noticed something odd. While I have something like 3000 songs on my phone, my iTunes library on my pc (running Windows 11) has only about 300 songs. I cannot recall the last time I checked, but in the past all 3000 or so of the songs currently on my phone were in my iTunes library on my pc. Now they have disappeared. Checking further, I see that there is nothing on the pc's iTunes library from before 2021 (including CDs I'd put on there and songs and albums I'd purchased from the iTunes store). I thought this was weird, but figured that I could just sync from my iPhone back to the pc, but that did not happen, as the sync was only for the few songs left on my pc. My phone is updated to the latest IOS (just updated today), and my pc is also up to date on iTunes. I am pretty sure this issue is recent, as I can clearly recall seeing some of the songs now missing in my iTunes library on my pc in June when I got my new iPhone (I previously had a 2020 iPhone SE). At this point I don't want to try to sync the phone and pc until I see what suggestions you have, as I would not like to lose the songs I have on my phone.
