Ever since the rise of Pandora’s audience there has been an effort to try to position the service as “not radio”. I understand the defensive posture that terrestrial radio would like to take but in my view anything that competes with you is probably quite similar in nature. Consumption of audio takes many forms but in the end there are only so many hours in a day. Listening to Pandora most likely means less time spent listening to terrestrial radio (or did all of the 69.5 million active Pandora users never listen to terrestrial radio?). We can argue about which form listeners prefer. Currently terrestrial radio has the lion share of listening. Pandora’s audience seems to have peaked.
Frankly I’m surprised that Pandora has not attempted more music curation and localization (they certainly have the user data given registration). Could I choose which version I want? Time will tell.
