CopyTrans Manager can read the following file types: .mp3, .m4r, .m4a, .aac, .wav in your iPhone library. These may be music files, videos, ringtones or audiobooks that you downloaded directly from PC, from iTunes or purchased through iTunes App Store on your device.
The tracks that you bought from iTunes App Store are considered as cloud music.
CopyTrans Manager can see the purchased tracks that have been downloaded on your device and the ones that have been deleted from the device but are still in the list of purchased tracks in iTunes App Store. The downloaded tracks are grayed out and marked with a “cloud” icon. 
The tracks that have been purchased but then deleted from the device are marked with a “cloud” icon and an exclamation mark. 
CopyTrans Manager also detects Apple music tracks. You can see them marked with an apple sign in the interface.
