I have a new iPhone 15. My music, 1200 songs did not transfer to my new phone form iCloud. How can I get it to my new phone?

Hello Aluisus,

Thanks for asking the Apple Support Communities about transferring music.

Turn on Sync Library. Use Sync Library with your Apple Music subscription - Apple Support

Be aware, if that's on, it might be still syncing. Some music showed up, other is still syncing with iCloud.

If you still don't find them, make sure you have Sync Library enabled on the older device, and verify you have iCloud Storage space available: Manage your iCloud storage - Apple Support

"If you run out of iCloud storage, your device won’t back up to iCloud, new photos and videos won't upload to iCloud Photos, and iCloud Drive and other iCloud apps won't stay up to date across your devices. And you also won't be able to send or receive emails with your iCloud email address."

Thanks.
