track count error?

after exporting a fresh database to a new drive i noticed that the number of tracks i have in my collection (in rb) is more than whats in my completely exported play list count (in the tracks folder on the new exported drive).... i thought the tracks folder should say the same number as whats in your rb collection!

that clearly means i have some collection tracks that arent in a playlist...

any easy way to locate these bad boys?

or is there another reason for the differing track count?

everything else pans out with itunes - from where all my play lists originate... its just a bit odd.. my ocd is going mad right now!!!
