Match my CD's library with Apple Music (subscription)

Hi the community,

In Apple Music, I wanted to know if there is any possibility to have an easy way to match my library (which contains my own CD's) with the music from Apple Music (Already have a Subscription).

I created multiple Playlists I want to share with my Car and different Devices and I would be OK to re-add (duplicate) the same song from Apple Music to my library but there is many issues with that. Most of the time it doesn't add the same song from Apple Music to the library when it exists locally through my CD's. Which in that case, doesn't share the song with my other device. Even if I have activated the "sync my library" the other devices it still keep saying "This song is not across your devices" for most of the song (even if it's seems working for a few).

Your help is welcome :-)

have a great day.
