I have several songs on googles youtube music app that were purchased from google play. How do I transfer those songs to my iphone 11 music playlist? I also have some older songs on my iphone that are not on the music app. How do I also add them to my Apple music playlist?
The only way I know of is to use a computer (with iTunes installed or a newer Mac). First you will need to import those songs to your computer. Then use the computer to sync those songs to your iPhone.
