That's a tough nut with Christmas songs, since there are 100 versions of the same 25 songs. But that explains the problem we're having.
It's also pretty bad with standards.
How many different versions of "Sunny Side Of The Street" are there?
"Take Five" ?
"All Blues" ?
"Eleanor Rigby" ?
Just to name a few. Using just the file name is, with all due respect, not the best way to do this, as it presents a very clear imposition on just what a person may be able to import.
Putting the track number into the song title filename is a very poor workaround, as the song title does not include ... any track number.
Using the full path would be the correct, and ideal, solution, I believe, as it makes every instance of a file a unique occurrence, and it's more representative of the real world situation that we all encounter.
My music collection consists of around 24500 titles, and I'm just starting to dupilcate a lot of that in HD, so, again, the titles will be the same, although the paths will be quite different.
I can already see that there's about 1000 tracks that have been not imported because they've been, incorrectly, IMHO, flagged as dupes, and from what I'm seeing, any new HD tracks that I try to bring in will also be rejected.
Again, and with the greatest of respect, I believe that this does need to be reviewed.
