How to import music videos into the Music app on a MacBook Pro?
The solution is not to go to file and add as that does not work, it took me ages to figure it out.
First go to you media folder then next the music folder create a Music Video Folder then drag all your music videos into that folder. Now go back to file then import and select the entire folder or individual MP4 files and then open and thats how I got my music videos into the music app.
Apple have created ways to prevent you from adding files that aren't bought through them.
