I;m new to having a MacPro laptop so not sure how this works. I have a Samsung S5 android phone. I want to copy my music from the phone to my MacPro. Basically so i have it in case phone or SD card in the phone take a crap, and also just so I can have my music on my computer as well. What is the easiest way to do this??? Does it have to be in iTunes to be played and saved? Say a month from now, i have 20 more songs new on my phone and i want to add those to existing music I had already saved a month earlier, will it copy all the music again or will it just copy my new music over?? i dont want to copy duplicates of same songs on the Mac.. also, if i move them onto my Mac, that music will stay on my SD card on my phone as well, correct??
