At RadioSEGA (www.radiosega.net), we're now looking into alternatives for the software that we currently use to manage our station.
We're impressed as to what Airtime can do, however one feature appears to be missing or not explained.
RadioSEGA has live shows, and when there isn't a live show, the software automatically queues up tracks so that we have a 24/7 music station.
One of our main features at RadioSEGA is the ability for listeners to browse our playlist and request tracks, which in turn get queued and then played on air during the automated DJ time. I haven't seen anywhere on the Airtime website about the ability for listeners to make track requests.
