Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
On your iPhone, go to Settings > Music and sign out of home sharing if you are signed on to it. Then open Music app, tap the profile icon at the top left and if you see your account signed in there, then Sign Out.
Then open iTunes on your computer. Click on the Music icon at top left. Click iTunes Store. In iTunes Store, click on Purchase on the right. This will bring Purchase history screen. Click on "Not in My Library" tab and download all. This will download all musics to your iTunes.
Now click on your iPhone icon at the top left. Select Musics tab. If "Sync Musics" is enabled, then disable it and click Apply. Then enable it back and click Apply or Sync again.
Please let me know if that didn't work, so we can continue troubleshooting.
Hi Durinda, Screenshot of which part ? iPhone part or iTunes of PC part ?
Apple ID would be your email address.You can find it from this website --> https://iforgot.apple.com/password/verify/appleid#!§ion=appleid
Downloading to both are same. There is a chance the musics are on cloud and that is why they are not syncing. Downloading from purchases will download an offline copies of those muiscs which can be synced to iPhone.
This part is very important:
In iTunes, click on your iPhone icon at the top left. Select Musics tab. If "Sync Musics" is enabled, then disable it and click Apply. Then enable it back and click Apply or Sync again.
Let me know how it goes
