Hi goodknifehk,
had any success? I have run more tests. I have the same problem as you with Hotmail, but can send from iReal book to my ISP-related email address (and a couple of others, not hotmail) and use webmail to Copy/Copy link into our web editor. One of my thoughts is that the generic hotmail (perhaps gmail also) change the code of the song somehow. If you could try with a different email address it might work for you.
I want to do some more testing so if I come up with anything, will post back here.
Thanks.
