The other thing about scheduling banter between songs is that you play less songs per livestream, because part of that time is taken up by chatting. That means that people aren't going to hear the same songs so often, and if you've got an extremely limited setlist, that's going to be pretty handy.Having a guest stay for the entire show and give opinions on the song/general banter between songs would work a lot better than what we have now, but i imagine that'd be more difficult to schedule. And, as already pointed out, Phase doesn't have that much music to not get repetitive fairly quickly.
In general, i like the initial concept of a radio-show, and Dizzy's got the host persona nailed down, but the overall execution is quite undercooked.
