If you have downloaded some new music to your iPhone, or you've just found your long lost iPod with some great nostalgic tunes on, it may be the case that the iTunes library on your computer is not up-to-date with all of the music on your iPhone. Unfortunately, iTunes cannot scan your iPhone and show you the difference in music. Find out how TouchCopy can help you by providing a list of the iPhone's music which is not showing up in your iTunes library.

When you start up TouchCopy and connect your iPhone, iPod or iPad, the Music Tab will open by default, displaying songs and playlists on your device. By this point, TouchCopy will have already scanned your iTunes library and compared it to the contents of the library on your iPhone, iPod or iPad. TouchCopy will detect all music stored in your device's library, i.e. any songs you purchased on iTunes, or tracks that were synced to your device, for example from your CD collection.
Click the "Not in iTunes" header on the left of TouchCopy, and the software will give you a list of the tracks on your iPhone, iPod or iPad which are not yet showing in your iTunes library. When you see the "Not in iTunes" list in TouchCopy, simply click the "Copy to iTunes" button to copy the missing songs into your iTunes library!
