"When I plug in my iPhone into my computer and try to sync my playlists on iTunes to my iPhone, the sync completes but the songs will not be transferred. I have literally tried everything that I know. Why iTunes won't add music to my iphone 6s? Any suggestions would be appreciated?"
Anyone who's had iTunes for a few years has probably run into this problem, especially those who have just upgrade iOS (for instance, upgrade to iOS 10/9.3/9). Here are 7 most reliable solutions for you to solve this annoying problem.
iTunes won't transfer music to iPhone after iOS 10/9 upgrade? If your iPhone won't sync music with iTunes, one of the most common reasons is the iTunes media files missing or corrupted on your device. Tenorshare iCareFone (iPhone Care Pro) offers you a chance to restore lost or corrupted iTunes media files easily and at the same time you can sync all or partial music, ringtones between Apple iOS device and PC/iTunes library without iTunes.
Music, especially HD ones usually take up large space, and you can't move songs from iTunes to iPhone if you don't have enough space for all the songs. To find out how much space is left on your iPhone, you need go to Settings > General > Usage > Storage. Under Storage you will see how much space you have left on your device.
If you don't have enough space, you should clean up iTunes library and save more space for new songs.
Sometimes iTunes does not indicate which songs it cannot find until you select them. If iTunes can't locate songs in your library, iTunes won't transfer music to iPod touch or to your iPhone and iPad. Double check if the songs on your iTunes library have same folder location as before.
In iTunes when you select your iPhone, go to the Music tab - is "Entire music library" selected? If so, go to Music (in your iTunes library), click on the check mark next to the "Name" column header (to sort by checked music) and scroll to the bottom. Any unchecked music won't sync.
Sometimes, the iTunes version might cause the iTunes won't sync music issue. In this case, you need to see if you are with the latest iTunes (click to download iTunes 12). From your iTunes, go to Help > Check for Updates if you are a Windows user; Mac users go to iTunes > Check for Updates.
In order to put your music on your iPhone you have to put your songs into a playlist and then sync up that playist to your iPhone. Use the Audio tab in your iPhone config to select all or just some of the playlists to sync up.
The overall guide goes like this:
Highlight all the songs you wanted to sync, right-clicked "Add to Playlist", and selected the playlist that appeared automatically with the name of your iPhone.
Corrupted or missing iTunes library files will cause iTunes won't transfer music to iPhone. In this case, you need to rebuilt the iTunes library. Free TunesCare gives a the easiest way to repair corrupted iTunes/iPhone Library (iTunesDB and iTunesCDB files) with only 1 click.
