I figured it had something to do with duplicate tracks. But that still doesn't explain why I see about 400 tracks too little
Tony, yes as a matter of fact I do have a few 'ignore as child' albums. I'll add them again and see if the problem disappears.

edit: yup, it's the 'ignore as child' tag alright. I just untagged 200 tracks and the player now sees 200 tracks more.
I must have had about 400 'ignore as child' tracks.
