First I want to say that i love the app! Keeps getting better and better. Since 4.2 came out, I have one concern, and one suggestion that I hope you'll consider.
First, the concern has to do with guest permissions in clubs. I want to prevent guests from listening to music, but the group permissions are not accessible when it is inside a Club. Would there be a way to disable guests to listen, site wide, and only allow signed in members (or specific user groups) to use the "listen" feature. I mostly just want to disable guests to be able to listen to music inside a public or open club.
Second, my suggestion. I notice on other music stores a cool feature called "Pay what you want". So basically allows the buyer to enter their own value for the song, if the musician decides to use the feature.
