I hate spending lots of money on DAB infrastructure right before it turns outdated and irrelevant. The future is internet. Many are now switching from FM to Spotify or internet radio on 4G and ignoring DAB.
DAB doesn't cost me per minute listened. I'm on a very good mobile plan here in Australia (10GB for $40/month) that would finally mean I could stream (128kbit, blech) music all day and not immediately hit the data cap. Many people aren't on that kind of data cap though. Not to worry - there wasn't ever any mobile data net neutrality so Spotify, Apple Music and Netflix aren't included in the cap (with a quality limit, of course)
