Scotty,
I downloaded a playlist from a pen drive on my desktop and it is not syncing to my iPhone music. I have tried everything Incan think of. Any ideas?
Thanks,

There can be many reasons this has not succeeded. Let's discuss a few:

* The music may be from a different iTunes account and are not authorized to be played on your computer. If the music shows up in iTunes after dragging, you can double click to see if the track plays. If not, you can right click and get info then under "File" you can see if it was a purchased item.

* The file may just be unchecked in iTunes. Unchecked songs do not sync.

* Music could be an incompatible format. ex: wma, mkv, rm

*The "playlist" being drug may not even contain any music.

*iTunes may not be syncing music to the iPhone manually. There are other services such as iCloud music library or iTunes Match that move music to the iOS device over the internet instead of over a wire during a direct sync.

These are only a few possibilities. I would need more information to help more.
