OK, look...this is like wondering why you can't find anything like the Hope Diamond at your local jewelry store - even if it is Graff Diamonds.
You have some rare or limited things that aren't going to show up, so, apparently, you're gonna have to fill in the info.
When you take the title Takussaanou Ndakarou and it doesn't even show up in Google(!) -
except for 4 cases of a variation on that, then you know that you've got something rather limited
and off-the-radar. Rare kalindula or exotic radif and tasnifs? - some of these will be hard to find
(but not all because I usually have good luck with them). Zani Diabate's Tientalaw, on the other hand? - no prob.
Here's the website for Song Sergeant which is the main one that I use for big jobs.
Yes, it checks for artist variations - giving you what it thinks should be correct, but you can change this if you don't agree
(Imagine the different ways that, for instance, Booker T. & the M.G.'s, might be shown in your library).
"latin" and "Latin" are different if you're an exacting piece of software which is very helpful in most instances.
I have another, even more detailed piece of software for things like "genre" and "BPM" a.o.,
but I can't remember its name at the moment and I need to check with this soon anyway.
When I come across it during a spot of time, I'll let you know.
Also, I wanted to mention that sometimes I pick up Ethiopian and Eritrean discs in small shops
during my travels and about 40% of them don't show up in the database either, so...
i would never ignore you Rod!
