Can't upload my Music Videos to iCloud Music Library

[andrew633]

Please, I need Help!
I have a big bunch of Music Videos (MPEG-4 video files) which I downloaded from YouTube using YouTube Downloader app. All the music videos play and work fine in my iTunes but my problem is when I try to upload them to my iCloud Music Library they won't upload and I just get a 'Waiting' download status icon, nothing happens. Ive tried updating my iCloud Music Library over and over, Ive also signed out of iTunes Match and Apple Music then signed in again, but nothing changes. Has anybody got any suggestions please?

ps I have just noticed that all of the Music Videos (MPEG-4 video files) already stored in my iCloud Music Library are "Protected MPEG-4 video files" or "Purchased MPEG-4 video files"..
