I downloaded the first of those, and looked at them only to find I already have them! If nobody has put them on FileFront in the next couple of days I'll do it.
On the other hand, I still have a copy of my favorite, the German Hits series. For my own use I converted them to .wav files, and then somehow managed to dump the .ogg files.
I'm busy converting them back to .ogg format. When I'm done I'll put them all up on FileFront and post it here. You'll be amazed at some of the stuff on there, going all the way back to 1912.
