Duplicaten selecteren uit een enkele rij?

Dit zou het omgekeerde krijgen (dwz de duplicaten overslaan):

SELECT c1.*
  FROM CoreTracks c1
      ,(SELECT Title, ArtistID, MAX(FileSize) AS maxFileSize, MAX(BitRate) maxBitRate
          FROM CoreTracks
          GROUP BY Title, ArtistID) c2
  WHERE c1.Title = c2.Title
    AND c1.ArtistID = c2.ArtistID
    AND (c1.FileSize = c2.maxFileSize OR c1.BitRate = c2.maxBitRate)

En de duplicaten:

SELECT c1.*
  FROM CoreTracks c1
      ,(SELECT Title, ArtistID, MAX(FileSize) AS maxFileSize, MAX(BitRate) maxBitRate
          FROM CoreTracks
          GROUP BY Title, ArtistID) c2
  WHERE c1.Title = c2.Title
    AND c1.ArtistID = c2.ArtistID
    AND (c1.FileSize != c2.maxFileSize AND c1.BitRate != c2.maxBitRate)
