Duplicate That Flags Case Change

I'm using the standard duplicates query on a field called trackTitle:

SELECT TrackTitles.trackTitle, TrackTitles.akTrack
FROM TrackTitles
WHERE (((TrackTitles.trackTitle) In (SELECT [trackTitle] FROM [TrackTitles] As Tmp GROUP BY [trackTitle] HAVING Count(*)>1 )))
ORDER BY TrackTitles.trackTitle;

I need to be flagged if there's a title in a different case - for example, the track "NEXT Year" might have versions appear as "Next Year" or "next year". These versions would need to be flagged and then corrected by hand.

Eyeballing a list of 4,000 new tracks isn't cutting it.

If I could get the duplication to be case sensitive, I could then use a left([trackTitle], 5) to weed down the review list - much easier to pick out the thorns.

Any ideas on how I could make that duplicates query case sensitive?

Thanks.
