I have a large library of music that I've ripped from CDs. I don't really have space left on my macbook air, but I have a bunch of space on my iPhone still. Is there any way to load that music into my iPhone's version of iTunes without keeping it stored in duplicate on my laptop?
A note to be careful to leave the “keep music folder organized” setting unchecked unless you really do want iTunes/Music rearranging all the files on your music drive.
