How to copy MP3 files from my PC to my iphone? I have many Mp3 on my PC but some Mp3s I want to copy in iphone to listen from iphone. How to do that? I'm having itunes account and itunes software on my PC but unable to copy MP3s to iphone.
With Catalina macOS (1.15+) iTunes is gone.
You will need to open Music application & click under the File and chose Import...
After the mp3 files are imported; you can sync music via Finder by clicking on your iPhone's icon within a Finder's sidebar. Then click Music & check Sync music onto My iPhone.
