Hi, I hope this is the right place to ask this, I really need an answer. I recently upgraded from "iPhone 6S 64gb" to "iPhone 7S plus 32gb" and I'm struggling with the lack of space! Do I have to have all my songs synced to my phone with iTunes in order for them to appear in Spotify? I have about 15GB of music and I'm struggling to cut down space to migrate to my new phone. I hope I've made the question clear enough, pleeease help me?!
