"I want to transfer my songs from the Samsung Galaxy phone to PC, but I can't do that with just a USB cable. So, what do I need to get it done?"
Well, in most cases you can do as the following: Open "Setting" > Enter "More…" > Tap "USB utilities" > Check "Connect Storage to PC". Then the mass storage mode will be enabled. You may now open up your PC Windows Explorer and find the removable disk. If the location of the music is known, data transfer would be easy. But, I could not find anything like "USB utilities" on my Galaxy S3. So, there is no way to proceed to the last step. Luckily, I find two ways to do it — Samsung Kies
and Mobile Transfer
Though you have to install the program first, it is really worthwhile. Only two steps are needed for both applications to backup your music from Samsung devices to PC.
Part One: Backup Samsung Audios with Samsung Kies
Part Two: Perform a Backup of Samsung Songs with Mobile Transfer
