How to add music from PC to iTunes
I was having difficulty adding music from my PC to my iTunes library.
Guess what???
You can't have your phone connected to the computer (iTunes) when adding music to the iTunes library.
1 - Eject your phone from iTunes
2 - Drag either individual music files or folders of music from your PC into the iTunes music library
3 - Connect your phone to the PC (iTunes)
4 - Sync
Done!
Transfer Music from PC to iTunes
