[Tango-L] how many tangos?

[Oleh Kovalchuke]

I have been talking to someone at recent milonga, and someone has
asked me, if I get tired of dancing to the same old tangos. My answer
was no: the mood, the partner change the emotional meaning of the
dance all the time. Besides that, there are a lot of classic tangos I
have never had a chance to dance to yet. I have couple thousands
recordings by various tango dance orchestras from the golden age of
tango myself -- most of them I had never heard played at milongas.

Thinking about his question has piqued my curiosity though. Does
anyone know how many arrangements have been recorded by all tango
dance orchestras in the period from the late twenties to the fifties?
~20,000; 50,000; 100,000...?
