New iPhone user here.
I have a few mp3s from music that I recorded myself.
I cannot seem to find a way to add them to my phone.
I have them on 'Music' on my computer and can play them normally, however, when I try to drag them to my phone nothing happens ... I can do the same thing with any other mp3 but not these ones.
Am I doing something wrong? How may I accomplish this?
Edit: Some details I missed that you are kindly asking about. I'm using MacOS, using 'Music', the 'Music' app that used to be iTunes. And they are on my library already, I just can't make them appear on the iPhone. All other tracks work just fine, but these ones don't.
