Aristotle observed that man is a "social animal". That is the fundamental premise behind why there will always be room for "radio" in people’s lives.
I was reminded of this when listening to some podcasts this weekend. I rarely listen to terrestrial radio, save for NPR, preferring instead to listen to algorithmic, playlist-based streaming radio (like the sort that Launch or Rhapsody might offer). The podcasts, raw though they were, made me realize how much I miss having a live human introduce me to music in an intelligent way. I miss the personality and human touch that I love in great music shows like KCRW’s Morning Becomes Eclectic, NPR’s All Songs Considered, Virgin Radio (UK) and now in podcasts. Playlist-based, algorithmic radio works well for me when I’m working and can’t concentrate on another human voice. However, when I’m mobile (in the car or out and about), I’ll want a human voice, whether as part of a talk show, or a music show introducing me to music I might like.
