hey guys i just purchased a new imac. i used to have a dell laptop but it died. so i downloaded a few songs onto my new imac and would like to get them onto my iphone but it says if i sync it will erase the music already on my iphone. is there a way to transfer the music without erasing my existing library on my iphone? ive tried searching but i can only find ways to transfer music onto my imac from the iphone.
