> Every Red Book audio CD has an MCN (Media Catalog Number).  I suspect that the online databases use this as their index and as the primary search criteria.  When you import a CD to Tellico and get a dialog with multiple choices, I suspect that the underlying database has multiple entries under the same MCN.

If you use CDDB to query, then the ID is computed based on the length of
each track and their number. Which can lead to duplicates indeed. The
way it's generally solved is by chaging the category of the CD (rock,
classical, jazz, ...)

MCN would have been a better choice, if only it was accessible when you
query the CD :-(

Ah, I've never tried that before. Will check when I'm back at home to
see how this works on my Audio CDs
