Not trying to fud, but I was Wondering why you would integrate TOR and ANON for a music service?
I don't see the necessarity of it, or is it because that are functionalities which are popular?
Well, there's just no question - today it's a set of features of any cryptocurrency which expects to be universal.
I much more interesting in conceptual solutions for example integration services with ringtones or paid content.
If I were them, I would be engaged purse integration as well.
