Best way to merge music without deleting existing music on an IPAD
I have had issue with my ITunes library- many issues. I have a ITunes clean and sorted App on my PC laptop which I would like to keep intact. On IPad I have ITunes App that has many different added music files that I want to keep- in an ideal world I would merge one into the other, but need to do this without erasing content on either version.
I do have an ITunes sweeper software program that removes duplicates on the PC. Any ideas to best merge these two would be really appreciated
