Yes mules songs are nice and they sing frequently but still as good as a Canary IMO. My personal preferences is to keep strains pure and I've never had any interest in breeding mules and I've had the resources to do so as I have siskins and can easily obtain gold or Green finches for only a few bucks. People will do what they feel is right for them but I do understand where Eorix is coming from because where will it stop because people will be looking for the new thing like a oriental Green finch mule.
djb78 you're not wrong, I just love the songs of different species of Finches, I often have an early morning cuppa outside, near the aviary, and whatever I may be doing I can tell a Goldfinch song from a song of a Siskin. I also just love the songs of a Jacarini or a Strawbery finch, the crackling sound of young Javas or a soft song of a Gouldian finch. And Zebras are something special, many years ago I started with zebras and every time I hear a Zebra finch sing it brings back that "magic" of way back then. And the little annoying
early morning non-stop song of a Saffron Finch or a Chaffinch! If you can't appreciate that then why keep song birds at all?
But have done the Canary x Goldfinch in the past by foolish mistake. (There are canarys of both sexs so the solo Goldfinch will not be a problem 
) And the resultant young was a wonderfull singer and a beautiful bird, who saw out his days delighting me with his song and nature. So I can see the attraction.
