I'd like to be able to share my real-time listening information with friends (and neighbors) only.
also a friend of mine brought up another good idea of being able to sort friends appearing in your profile, say by 'now playing' or a custom selection.
I get the need for commercials on the custom radio stations, but do they need to be EIGHTY DECIBELS LOUDER than the regular music streams (and -- apparently -- everything else I play on my computer)? I nearly fell out of my chair.
