Sync itunes content to use in Music on Android

I recently decided to try to hear my former itunes collection in Music on my Android phone.

It syncs ok, but misses a huge number of tracks that were ripped from CDs and won't easily pull a playlist over.

I have checked all the id info and the allowed devices. I just want to listen to my music in my order.

Also how to turn off all the suggestions and additions to MY playlists.
