If you look at

you’ll see that Classical + World + Baroque genres, by sales, make up 46% of Magnatune’s sales, and all of that is public domain repertoire.

And the new age stuff on Magnatune is largely world-music-borrowing, so another 12% of our sales can be at attributed to “heavily leaning on PD”

As far as the # of albums go, I think about 40% of Magnatune’s albums are PD repertoire. I’d have to count the # of albums on the various pages to get the exact count.
