*** Possible Solution ***
I initially started to use
Easy Phone Sync, another app from the same company. First time, it worked great and fast. The free version also does multiple Playlists.
The problem I ran into happened when I changed some of the songs on my iTunes playlists. After updating my playlists, I was not able to sync again. It kept telling me that the phone is locked or tracks are broken.
So I installed Easy Phone Tunes as recommended by madlaw1071. At first, it hung. Stopping it and restarting it made it go very fast. But, was only able to do one playlist and took my other playlists off the phone.
Instead of upgrading to Easy Phone Tunes Plus to copy multiple playlists, I went back to Easy Phone Sync and was able to copy all my newly updated playlists pretty fast
Please note, your phone must be connected in Media Device Mode (MTP).
I have Samsung Note 2 and copying everything to a 64GB SD card. I hope this helps!
