Didn’t know I could revert to iTunes, thanks, might try that. Hoping song limit is eventually increased. I was told by Apple support that if a song appears on an album in your library and you add it to a playlist it’s stored on the cloud library twice, taking up 2 places in your capacity
That's not how any of this works.
Playlists are ordered lists of references to items in your own iCloud Music Library, or in some cases to items in the Apple Music Catalog if you haven't enabled the option to "Add songs to library when adding to playlists" or some equivalent. The same song can appear in multiple playlists without affecting the overall count of unique songs in the library.
