A few months ago I purchased an iPhone 5C to replace my 4S and changed over to it but when I couldn't drag music from my files to the 5C, I went back to the old 4S. An acquaintance told me it was more difficult to add one's own music to the 5C, but it was possible by uploading to iCloud (I think she said). The person is away now so I can't ask her. Is this easy enough to do? I want to go back to the newer 5C but really would like to have my music and don't know how to put it on the 5C. Can you help me with this?
