Second level domain transfer not going through

Hoping someone can help with this.

I recently purchased a new domain name from my.MUSIC, the official music community provider of .MUSIC domain names, specifically blackcalvary.music for use with my website. However, when I attempt a second-level domain transfer, I'm greeted by a submission form that doesn't allow wiggle room -- a wide variety of domains, to be sure, but not the one that I wish to use.

I understand that .MUSIC domain names are a fairly new, indeed likely niche, development, but it is the address I wish to use for my Altervista website nonetheless. Is there some way of working this out? I assume obtaining an Authinfo code would not be any different from other more standard domain names.

I suggest you to contact domini at altervista dot it directly to ask about this issue.

Bye!
