thanks to all of you, but at the moment I have to give up.
All too difficult for an application that should allow you to enjoy music calmly, with pleasure and at the highest possible quality. Considering then that it is a paid application, which leaves individuals to their own devices, having to climb through posts, generous users and perhaps even receive reproaches.
I belong to another century and therefore I don't like this type of relationship.
Perhaps I will return to JRiver more calmly, hoping to find the more mature, efficient and enjoyable app.
There are excellent free apps that easily allow you to have maximum quality and services, with remote apps that are equally free and functional. I think of Daphile or Foobar2000.
Thanks again and maybe see you soon.
