I lost all my iTunes music with new phone update
HELP! I have an older 2014 model MacBook Pro with the old iTunes. My phone is an iPhone 6s with the latest iOS 12 update. I have not joined Apple Music yet. All of my purchased iTunes music transferred. How do I get all of my non-purchased tracks that are sitting on my old MacBook (i.e. from old CDs, voice memos, downloaded .mp3s from who knows where) onto my iPhone? No, I don’t know if I used iCloud music library or not—I just remember everything transferred using iTunes WiFi sharing.
Thanks in advance.
